Write the slope-

intercept form (y=mx+b) of

the line given two ordered
pairs (4, -2), (-4, -4).
Don’t forget m = y2 − y1
x2 − x1

the slope is (-4+2)/(-4-4) = 1/4
so start with the point-slope form:
y+2 = 1/4 (x-4)
Now just rearrange that as you want.
slope = (-4+2)/(-4-4) = -2/-8 = 1/4

so y = (1/4)x + b
using the point (4,-2)
-2 = (1/4)(4) + b
-2 = 1 + b
b = -3

equation: y = (1/4)x - 3
