Melanie is saving for a new bike. She already has $75 in her savings account and she plans to save $20
each week until she can afford the bike.

1st answer choice

Step-by-step explanation:

Let me know if you need an explanation

A. y = 20x +75

Step-by-step explanation:

y is the amount of the bike because Melanie is saving for a new bike. That get's rid of C & D immediately.

$75 is the amount she already has so that can be a number on it's own without an x value

The answer is A because she is planning on saving $20 each week meaning if you were to solve this problem you would put the amount of weeks she saved and replace it with x. Then you would add the 75 dollars and get the amount the bike is (y).

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)
