(-4,4),(0,-2)
slope = (-2 - 4) / (0 - (-4) = -6 / 4 = -3/2
y = mx + b
slope(m) = -3/2
use either of ur points...(0,-2)...x = 0 and y = -2
now sub and find b, the y int
-2 = 0(-3/2) + b
-2 = b
so ur equation for this line is : y = -3/2x - 2
to turn it to function notation, sub in f(x) for y
f(x) = -3/2x - 2 <=== ur answer
