Question

Find the x-intercept and y-intercept from the following linear equation: 9x - 3y = -81

Answer 1

Answer:

The x-intercept is (-9,0). The y-intercept is (0,27).

Step-by-step explanation:

9x - 3y = -81

-9x         -9x                  Subtract 9x from both sides

-3y = -9x - 81                Divide both sides by -3

y = 3x + 27

I graphed the equation below.

Answer 2

Step-by-step explanation:

9x-0=-81

divide all through with 9x to get

x=-2

0-3y=-81

divide all through with 3y to get

y=27
