Step-by-step explanation:
The slope of a line is the ratio of the
A.
vertical change to the horizontal change between any two points on the line.
B.
x-intercept to the y-intercept.
C.
y-intercept to the x-intercept.
D.
horizontal change to the vertical change between any two points on the line.
Answer:
A.
vertical change to the horizontal change between any two points on the line.
Step-by-step explanation:
slope is the ratio of the vertical and horizontal changes between two points on a surface or a line. The vertical change between two points is called the rise, and the horizontal change is called the run. The slope equals the rise divided by the run: . This simple equation is called the slope formula.
The slope of a line is the ratio of the : A. Vertical change to the horizontal change between any two points on the line.
The slope of a line is the gradient of a line and it describes (represents) both the direction and steepness of an equation of a straight line.
Mathematically, the slope of a line is calculated by using this formula;
[tex]Slope. \;m = \frac{Change \; in \; y \;axis}{Change \; in \; x \;axis} \\\\Slope. \;m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Hence, the slope of a line is the ratio of the change in y-axis (vertical) to the change in x-axis (horizontal) of a line.
Additionally, the standard form of an equation of line is given by the following formula;
[tex]y = mx + b[/tex]
Where:
x and y are the points. m is the slope. b is the intercept.In conclusion, the ratio of the vertical change to the horizontal change between any two points on the line is the slope of a line.

A line passes through the points (−4,−9)
and (−2,−6) What is the equation of the line in Slope-Intercept Form?
Answer:
D. [tex] y - 5= 3(x - 1) [/tex]
B. [tex] y = \frac{3}{2}x - 3 [/tex]
Step-by-step explanation:
Problem 1:
Point-slope form equation is given as [tex] y - y_1 = m(x - x_1) [/tex], where, (x1, y1) is a point on the line, and m = slope.
Find the slope of the line of the graph given, using 2 points on the line, points (0, 2) and (1, 5).
[tex] m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{2 - 5}{0 - 1} = \frac{-3}{-1} = 3 [/tex]
Substitute (x1, y1) = (1, 5) and m = 3 into [tex] y - y_1 = m(x - x_1) [/tex]
[tex] y - 5= 3(x - 1) [/tex]
The answer is D.
Problem 2:
Slope-intercept equation takes the form: [tex] y = mx + b [/tex], where, m = slope, and b = y-intercept.
Find m and b.
Given, points (−4,−9) and (−2,−6),
[tex] slope(m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-6 -(-9)}{-2 -(-4)} = \frac{3}{2} = \frac{3}{2} [/tex]
Substitute x = -2, y = -6, and m = ³/2 into [tex] y = mx + b [/tex], to find b:
[tex] -6 = \frac{3}{2}(-2) + b [/tex],
Subtract b from both sides
[tex] -6 = -3 + b [/tex]
Add 3 to both sides
[tex] -6 + 3 = b [/tex]
[tex] -3 = b [/tex]
[tex] b = -3 [/tex]
Substitute m = ³/2, b = -3 into [tex] y = mx + b [/tex]
[tex] y = \frac{3}{2}x + (-3) [/tex]
[tex] y = \frac{3}{2}x - 3 [/tex]
The answer is B.

On a test, Marcus is asked to simplify . Here is his work:
√128 = √16 · √8 = 4√8
Which statement best describes Marcus' answer?
He is incorrect because 16 times 8 is not 128.
He is incorrect because he did not use the largest perfect square.
He is incorrect because the 4 and the 8 should be switched around in his answer.
He is correct.
Answer:
He did not use the largest perfect square
Step-by-step explanation:
4 [tex]\sqrt{8}[/tex] is the correct answer
What is square root ?
In mathematics, a square root of a number x is a number y such that y² = x; in other words, a number y whose square is x. For example, 4 and −4 are square roots of 16, because 4² = ² = 16. The square root of any number can be expressed using the formula: √y = y½. In other words, if a number has 1/2 as its exponent, it means we need to find the square root of the number.
Given,
[tex]\sqrt{128}[/tex]
we divide the number 128 by 2 four times, we get
= [tex]\sqrt{8*2*2*2*2}[/tex]
= 2*2[tex]\sqrt{8}[/tex]
=4 [tex]\sqrt{8}[/tex]
Therefore, 4 [tex]\sqrt{8}[/tex] is the correct answer

Lorenzo has 4 packages of granola bars. Each package has 10 bars. He eats one bar from each package.
Answer:
4x10-4=36
Step-by-step explanation:
Lorenzo ate 1 bar from each. so 36 is left.
Answer:
4 × 10 - 4 = 36 granola bars
Step-by-step explanation:
4 packages with 10 bars each means 40 bars (4 packages × 10 bars each = 40 bars total)
one bar from each package
there are 4 packages so if he eats only one from each then he eats 4 bars total
40 bars total - 4 bars he ate = 36 bars left over

How does 8 × 2 1 3 compare to 8? A) Less than 8 because you are multiplying by number less than 1. B) Greater than 8 because you are multiplying by a number less than 1. C) Less than 8 because you are multiplying by a number greater than 1. D) Greater than 8 because you are multiplying by a number greater than 1.
Answer:
Greater than 8 because you are multiplying by a number greater than 1.
Step-by-step explanation:
When 8 is multiple by another number, say x, the product is;
I) less than 8 if x<1
ii) equal to 8 if x=1
iii) greater than 8 if x> 1
Since 213 is greater than 1,then the product of 8 × 2 1 3 is greater than 8.
what does k= 9k=8k-6
Answer:
Alright, so we got k + 9k = 8k - 6.
This means that 10k = 8k - 6.
As a result, we have 2k = -6, and k = - 6/2 = -3
So, k = -3 :)

give a numerical example that shows these are not the same expressions. 2(n+5) and 2n+5
Answer:
The two are different expressions because when you distibute, you multiply all terms inside the parenthesis with the 2 in the first one: 2(n+5) = 2n + 10.
2n + 10 ≠ 2n + 5.
Step-by-step explanation:
Answer: Any number that isn’t 1, 2, -1, or -2 I believe.
Step-by-step explanation: In the first expression, you have to distribute the 2, making it equal to 2n + 10, whereas the first is just 2n + 5.
For example if you were to plug the number 3 into this, you would have 2(3+5), which is 2(8) = 16. Versus the other side, 2(3)+5 = 11

Answer:
m<1 = 39
m<2 = 51
Step-by-step explanation:
For this problem, you need to understand that a little square in the bottom of two connecting lines represents a right-angle (an angle this 90 degrees). This problem, gives you two relationships for angle 1 and angle 2 within a right-angle. Using this information, we can solve for the measures of the two angles.
Let's write the two relations:
m< 1 = 3x
m< 2 = x + 38
And now let's right an equation that represents the two angles to the picture:
m<1 + m<2 = 90
Using this information, let's substitute the expressions we have for the two angles and solve for x. Once we have the value of x, we can find the measure of the two angles.
m< 1 + m< 2 = 90
(3x) + (x + 38) = 90
3x + x + 38 = 90
x ( 3 + 1 ) + 38 = 90
x ( 4 ) + 38 = 90
4x + 38 = 90
4x + 38 - 38 = 90 - 38
4x = 90 - 38
4x = 52
4x * (1/4) = 52 * (1/4)
x = 52 * (1/4)
x = 13
Now that we have the value of x, we simply plug it back into our expressions for the m<1 and m<2.
m<1 = 3x = 3(13) = 39
m<2 = x + 38 = 13 + 38 = 51
And we can verify this is correct with the relational equation:
m<1 + m<2 = 90
39 + 51 ?= 90
90 == 90
Hence, we have found the values of m<1 and m<2.
