What is the equation of the top line graphed below?

A. y = mx + b
B. y = b(mx)
C. y= mx - b
D. y=1/b(mx)

answer:

a

Step-by-step explanation:

b= the y intercept

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)
