What is an equation for the line that passes through points (4, -4) and (8, 4)?

a. (y - 4) = 2(x + 4)
b. (y + 4) = 2(x - 4)
c. (y - 4) = -2(x + 4)
d. (y + 4) = -2(x - 4)

Respuesta :

The answer is b. (y+4) = 2(x-4) because if you plug in both of the points to that equation, the right side of the equation will equal the left side.
(-4+4) = 2(4-4) which leads to 0 = 0
(4+4) = 2(8-4) which leads to 8 = 8
The answer is option a.
