See a solution process below:

The line $x = -9$ is a vertical line where for each and every value of $y$ , $x$ will equal $-9$ .

By definition, the slope of a vertical line is undefined.

because this is a vertical line at the $-9$ point on the $x$ -axis, there will be no y-intercept.

The $x$ intercept will be: $(-9,0)$ .

What is the slope and intercept of x = -9x = -9?
