Use the third pair of points to do each of the following. The third pair is (-6, 7), (-3, -4).
1. Give the slope
2. Write the equation in point-slope form.
3. Write the equation in slope-intercept form.
4. Write the equation of the line in standard form.
5. Give the x-intercept from standard form (remember, let y=0)
6. Give the y-intercept from standard form (remember, let x=0)
Answer:
The slope of the line is m = −11/3 ≈ −3.66666666666667 .
Step-by-step explanation:
The slope of a line passing through two points P=(x1,y1) and Q=(x2,y2) is given by m=y2−y1x2−x1.
We have that x1=−6, y1=7, x2=−3, y2=−4.
Plug the given values into the formula for a slope: m=−4−(7)−3−(−6)=−113.
Now, the y-intercept is b=y1−mx1 (or b=y2−mx2, the result is the same).
b=7−(−113)(−6)=−15
Finally, the equation of the line can be written in the form y=b+mx:
y=−15−11x3
Please help ;-; ASAP QnQ
in 2005 8.1 x 10^10 text messages were sent in the united states. in 2010, the number of annual text messages has risen to 1,810,000,000,000. about how many times as great was the number of text messages in 2010 than 2005?
find x and y if p || q and m3=(4x+6y),m5=86,and m6=(5x+6y)
Answer:
(8, 9)Step-by-step explanation:
3 and 5 are vertical angles and are equal as per definition of vertical angles
4x + 6y = 865 and 6 are supplementary angles and sum up to 180 as per definition of supplementary angles
5x + 6y + 86 = 180 ⇒ 5x + 6y = 94Comparing the two equations
6y = 86 - 4x and 6y = 94 - 5x86 - 4x = 94 - 5x5x - 4x = 94 - 86x = 8Finding y
6y = 86 - 8*46y = 86 - 326y = 54y = 9Answer

What would be your next step?
14p - 8 = 22 + 20p
-8 = 22 + 6p
The next step to solve the equation is subtracting 22 from both sides.
Thus, option (B) is correct.
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
Given equation: -8 = 22 + 6p.
1. Start by isolating the variable term, 6p, on one side of the equation.
In this case, subtracting 22 from both sides of the equation:
-8 - 22 = 22 + 6p - 22
-30 = 6p
2. Next, divide both sides of the equation by 6 to solve for p:
-30/6 = 6p/6
-5 = p
Therefore, the solution to the equation is p = -5.
Thus, option (B) is correct.

Write a direct variation equation that relates 16 and 2
Answer: 16 = 2x
Step-by-step explanation:
The pattern for a direct variation equation is y = kx.
y is the "output" or result.
k is the "constant" a number that will remain the same.
x is the "unknown" or variable that will make the output correct once found.
Here, x = 8

Answer:
For the first one, you get x<7.
For the second one, you get x >_ 11
Step-by-step explanation:
For the first one: -2x - 2 > -16
Step 1. Add 2 to both sides.
-2x - 2 +2 > -16 + 2
-2x > -14
Step 2. Divide both sides by -2 and switch the sign
-2x/-2 > -14/-2
x < 7
For the second one: 2x - 1 >_ 21
Step 1: Add 1 to both sides
2x -1 +1 >_ 21 + 1
2x >_ 22
Step 2: Divide both sides by 2
2x/2 >_ 22/2
x >_ 11

can someone plss help me? Asap i still don't get the hang of Scale Factors
1. If the scale factor between the original and the image is 4, how many times larger is the perimeter of the image than the original?
2. If the scale factor between the original and the image is 0.5, how many times is the perimeter of the image than the original?
3.The perimeter of an original figure is 14. If the image has a scale factor of 6 from the original, what is the perimeter of the image?
4.The perimeter of an original figure is 64. If the image has a scale factor of 0.25 from the original, what is the perimeter of the image?
Problem 1
Answer: New perimeter is 4 times larger than the original
----------
Explanation:
This is because we are multiplying each side by 4 to make each side 4 times larger than the original.
Let's say we had a triangle with side lengths 1,2,3
The perimeter would be 1+2+3 = 6
Now multiply each side by 4
4*1 = 4
4*2 = 8
4*3 = 12
Then add up those new side lengths: 4+8+12 = 24
We see that 24 is exactly 4 times larger than 6
In more general terms, say the triangle has side lengths x y and z
The old perimeter is simply x+y+z
The new perimeter is 4x+4y+4z = 4(x+y+z) = 4*(original perimeter)
==========================================
Problem 2
Answer: New perimeter is 0.5 times larger than the old perimeter
In other words, the new perimeter is half as large
----------
Explanation:
The same idea applies as in problem 1. The only difference is that we're multiplying each side by 0.5 now
1/2 = 0.5
==========================================
Problem 3
Answer: 84
----------
Explanation:
We're using the same idea as the other problems above.
new perimeter = (scale factor)*(old perimeter)
new perimeter = (6)*(14)
new perimeter = 84
==========================================
Problem 4
Answer: 16
----------
Explanation:
Same idea as before
new perimeter = (scale factor)*(old perimeter)
new perimeter = (0.25)*(64)
new perimeter = 16
As you can see, if the scale factor is larger than 1, then the new perimeter will be larger. If the scale factor is smaller than 1, but still positive, then the new perimeter will be smaller.
Answer: The scale Factor is the number that you Multiply the Original Lengths by to get the new lengths.
1.) The new length is 4 times the original. 4× L
2.) The new length is 0.5 times the original. 0.5× L
3.) 84. 6×14 = 84
4.) 16. 64× 0.25 = 16
Step-by-step explanation:
For lines --- like sides, perimeter, and distance, Multiply the original number by the Scale Factor to get the new number. Or Divide the New number by the Scale Factor to get the Original.
(They ask that sometimes.)
__Also remember that length refers to lines__.
[ Area refers to Square Units. The Factor must also be squared. ]

The dimensions of a rectangular dining room are 18 feet by 16 feet. If a scale factor of One-fourth is used to make a scale model of the dining room, what is the area of the dining room in the scale model?
18 square feet
36 square feet
48 square feet
72 square feet
Given -
The dimensions of a rectangular dining room are 18 feet by 16 feet. i.e, length (l) = 18 feet and breadth (b) = 16 feetScale factor of One-fourth is used to make a scale model of the dining room.To find -
the area of the dining room in the scale model (A)Solution -
As we know, the area of rectangle = length of the rectangle × breadth of the rectangle
To state the dimensions of the scale model we will multiply 1/4 with the already given dimensions of a rectangular dining room. Hence, dimensions of scale model is 18/4 by 16/4.
Now,
Area = length × breadth
Area = 18/4 × 16/4 square feet
Area = 18 square feet
Therefore, the area of the dining room in the scale model (A) is 18 square feet.
Answer:
18 square feet
