Answer 1

y = -10x-32

Answer 2

Answer 3

saifoo.khan: how did you come to that answer?

Answer 4

(-4, 8) and (-3, -2)

m = (y2 - y1)/(x2 - x1)
= (-2-8)/(-3+4) = -10 = slope

y = mx + b

to find b sub one of the given co-ordinates, and the slope

-2 = (-10)(-3) + b
-2 = 30 + b
b= -32

:- y = -10x -32
