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.
