Question

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

Answer 1

By definition the line `y = 4` is a horizontal line where, for every value of `x`, `y = 4`.

Therefore, for `x = 0`, `y = 4` so the y-intercept is `4` or `(0, 4)`.

However, because this is a horizontal line where `y = 4` there is no x-intercept.
