Question

How do you find the slope and intercept of `x = - 2/5`?

Answer 1

This is an equation for a vertical line where for each and every value of `y`, `x` is equal to `-2/5`.

By definition the slope of a vertical line is undefined.

Also, because `x` is always `-2/5` for every value of `y`, `x` is never equal to `0` therefore there is no `y` intercept.

Answer 2

Undefined slope; `x`-intercept: `(-2/5,0)`

Explanation:

The line `x=` indicates that the line is vertical crossing through the `x`-axis. The slope of a vertical line is always undefined because if you did try to find the slope of this line via the slope formula, you would find that the denominator would be `0` so it's undefined. Additionally, since the line is vertical, it only crosses the `x`-axis and not the `y` so the `x`-intercept is the line `x=-2/5`
