# How do you find the slope and y intercept of x=-7?

Feb 9, 2016

I found:
NO slope
and
NO y-intercept.

#### Explanation:

Well, this equation represents a perfectly vertical line passing through $x = - 7$.
It has no slope because $x$ never changes so the slope (representing the rate of change of $y$ AS $x$ CHANGES) cannot be evaluated.
Slope=(Deltay)/(Deltax)=(Deltay)/0=???
Being a vertical line parallel to the $y$ axis it will never cross the $y$ axis giving no intercept.
