Find the equation that represents the linear function described in the table below. What are the x- and y-intercepts?

x values / -8, -4, 4, 6, 12
y values / -4, -3, -1, -0.5, 1

1 answer

P1(-8, -4), P2(-4, -3).
m = (-3-(-4))/(-4-(-8)) = 1/4.

Y = mx + b.
-4 = (1/4)*(-8) +b,
b = -2. = Y-int.

Eq: Y = (1/4)x - 2.

0 = (1/4)x - 2.
X = 8 = x-int.
