Question 238647
If the slope is undefined, then it is a VERTICAL LINE.  If it passes through the point (1,-2), then the equation is x=1, and the graph will be a vertical line approximately 1 unit to the right of the y-axis.  


It approximately looks like this:


{{{graph(300,300,-10,10,-10,10, 100x-99) }}}
