Pls help me i don't know the ansewr sadly. :(

B) 2.5

Step-by-step explanation:

One point (S) is at the '-2' marker and the other point (T) is on the '7' marker. The midpoint (R) is directly in-between points S and T.

This means:

====================================

Point R should be at 2.5.

B should the correct answer.

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
