Answer:
y=5/8x+4.5
Step-by-step explanation:
You have to do y-y divided by x-x so 7-2 which equals 5 and 4-(-4) which equals 8 so your slope is 5/8. For y-intercept, you have to do plug in one of your points into y and x in y=mx+b, so I used the point (4, 7) and I put 7 in the y spot and 4 in the x spot and I put the slope in the slope spot so now you have 7=5/8(4)+b. Next, you multiply 5/8 and 4 which gives you 5/2 or 2.5, so now you have 7=2.5+b. Then you subtract 7-2.5 which gives you 4.5 and there is your y-intercept and your whole equation is y=5/8x+4.5.
Andrew purchased some drinks and some chips. Each bag of chips cost $2.00 and
each drink cost $2.50. The expression 2x + 2.5y gives the total amount of money
spent by Andrew on chips and drinks. What is the meaning of the term 2.5y?
Answer:
2.5y=amount spent on drinks
Step-by-step explanation:
If chips are $2 and drinks are $2.50 and we do not know how many he bought of each, we put this into an equation which is
2x+2.5y
x=number of bags of chips while the 2 is two dollars per bag
so, if he bought 2 bags of chips 2(2)= $4 spent.
y= number of drinks and 2.5 is $2.5 per drink, so if he bought 4 drinks:
2.5(4)= $10 spent on drinks.

How do I find the domain and range?
Answer:
Another way to identify the domain and range of functions is by using graphs. Because the domain refers to the set of possible input values, the domain of a graph consists of all able input values shown on the x-axis. The range is the set of possible output values, which are shown on y-axis

What are some ways we can tell that 7x + 2 is not equivalent to 9x?
Answer:
To determine if two fractions are equivalent, cross multiply. To cross multiply, you multiple the numerator of the first fraction by the denominator of the second. Then you multiply the denominator of the first fraction by the numerator of the second. If the two numbers are equal, the fractions are equivalent
Step-by-step explanation:
How many more games will it take until tom and will have scored the same number of points
Answer:
Both players will need to play 7 more games to have the same score.
Step-by-step explanation:
Will makes 18 points per game and Tom makes 21 points per game. Will has a total of 483 points and Tom has 462 points.
We have to calculate the number of games Tom and Will need to play for them to have the same number of points. Since Tom makes more points per game, we're sure it will eventually happen.
Let's call x to the number of games that both players will play. Will will have a number of points equal to:
W = 483 + 18x
And Tom will have:
T = 462 + 21x
For both number of games to be equal, the equation to solve is:
483 + 18x= 462 + 21x
Move 18x to the right side and 462 to the left side:
483 - 462 = 21x - 18x
Operating:
21 = 3x
x = 21 / 3 = 7
Thus, both players will need to play 7 more games to have the same score.

To convert a Unit Rate into another, we have to add or subtract a Unit Ratio to the original Unit Rate.
To convert a Unit Rate into another, we have to multiply the original Unit Rate by one or two Unit Ratios.
To convert a Unit Rate into another, we have to obtain a denominator different than one.
It is no possible to convert a Unit Rate into another.
Answer: To convert a Unit Rate into another, we have to multiply the original Unit Rate by one or two Unit Ratios.
Step-by-step explanation:
Unit rates are usually convertible to other units using multiplication and division attributes to ensure equivalence depending on preference or units being converted. Once the ratio or proportion between the two units (original and target) have been obtained, the original Unit is multiplied by the ratio of the two units to obtain the target unit rate. This way both units are equivalent to each other.
A line segment that forms a right angle with another segment at its midpoint
is a
A. angle bisector
B. perpendicular bisector
C. regular polygon
D. rectangle
Answer:
B
Step-by-step explanation:
Please mark brainliest if I helped.
A line segment that forms a right angle with another segment at its midpoint is a perpendicular bisector.
Option B is the correct answer.
What is a line segment?A line segment is part of a line that is bounded by two distinct endpoints and contains every point on the line between its endpoints.
It can be measured by its length and is finite in size.
We have,
A perpendicular bisector is a line or line segment that cuts another line segment into two equal parts and forms a right angle with it.
The midpoint of the line segment is the point where the perpendicular bisector intersects it.
Therefore, if a line segment forms a right angle with another segment at its midpoint, it is a perpendicular bisector since it cuts the segment into two equal parts and forms a right angle with it.
Thus,
A line segment that forms a right angle with another segment at its midpoint is a perpendicular bisector.
