How do you find the slope and y intercept for #x = - 2/5 #?

This is one of those peculiar lines that has to be written with just a single variable.

#x = -2/5# means that no matter what the y-coordinate is, the x-coordinate will be -2/5.

Since the y-intercept is defined as the point on a function where the x-value is 0, and the x-value of this line never is 0, this function has no y-intercept. That means it is a vertical line, so it slope is 1/0, which is undefined (technically speaking, it is #+-oo#).
