Question 33070
THE type of line that has an undefined slope is a vertical line and a vertical line is of the form x = c.  So, we will not use the point/slope form, but go right into setting up the equation x = c. 

a vertical line is in the form x = c, where the x value is ALWAYS equal to the same value throughout, this means our equation would have to be x = -5. 

so the equation of the line is x = -5
or x+5 = 0
