Question

What is the slope of the line that passes through the points (-4,5) and (0, -5)? Choose the BEST answer!

m = -10/4
m = -5/2
m= 0
m = 5/2

Answer 1

m= -5/2

Explanation:

formula for slope(m) : ΔY/ΔX (change in y coordinates - change in x coordinates)

change in y coordinates: 5-(-5) = 10

change in x coordinates: -4-(0) = -4

10/-4 = -5/2= -2.5
