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

Answer 1

One of those odd lines that can only be written using one variable is this one.

#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#).

To find the slope and y-intercept for the equation x = -2/5, note that this is a vertical line passing through the point (-2/5, 0). Since it's a vertical line, its slope is undefined, and the y-intercept does not exist.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
