What is the x-intercept of - 6x-3y-18?

-6x - 3y - 18

To find the x-intercept, plug in 0 for y and solve for x.

-6x - 3 (0) - 18

Multiply 3 and 0

-6x - 18

Add 18 to each side

-6x = 18

Divide each side by - 6

Your final answer is x = - 3

The x intercept is where the line crosses the x axis or where y=0

assuming yo means - 6x-3y=18

set y to 0

-6x-3 (0) = 18

-6x+0=18

-6x=18

divde both sidesb y-6

x=-3

the x intercept is x=-3

if it was - 6x-3y=-18, then the x intercept would be x=3
