Question

Jordan wrote the equation for a linear relationship as y = -8x - 4. For what value of x is y equal to -20? *

Answer 1

x = 2

Explanation:

Given

y = - 8x - 4 ← let y = - 20 in the equation

- 20 = - 8x - 4 ( add 4 to both sides )

- 16 = - 8x ( divide both sides by - 8 )

2 = x

Answer 2

2

Explanation:

y=-20

-20=-8x-4

-16=-8x

x=2
