Question

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

Answer 1

See a solution process below:

Explanation:

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)`.
