what is the equation of the line through (-1, -2) with an undefined slope

Question

find the equation for my question  so I can write it down

Answer 1

An undefined slope means that the line is vertical.  That means that it can take on any value of y, but only a specific value of x.  Since the x value of the point is -1, the equation of the line is x = -1.

 

 

Answer 2

A line with undefined slope, or no slope, is a vertical line.

 

x = -1.
