Then the graph is #x=-12#

If the slope is undefined then it means that

Slope (gradient) #->("change in y-axis")/("change in x-axis") ->("change in y-axis")/(0)#

So there is no change in the x-axis implying that the graph is a line parallel to the y-axis.

As this line passes through the point #P_1->(x,y)=(-12,0)#

Then the graph is #x=-12#
