Question

How do you find the x and y intercepts for `x=4`?

Answer 1

The x-intercept is `4`
There is no y-intercept.

Explanation:

The x-intercept is the value on the X-axis where the equation crosses the X-axis (i.e. the value of `x` when `y=0`);
`x=4` crosses the X-axis at `4`.

The equation `x=4` is a vertical line which does not cross the Y-axis and therefore there is no y-intercept.
