Question

How do you graph line through the point (5,-3) with undefined slope?

Answer 1

see explanation

Explanation:

The line with undefined slope means that the line is parallel to the y-axis (If you tried to measure it's slope you would get division by zero which is undefined)

The equation of the line is x = a , where a is the value of the x-coordinates that the line passes through.
In this case it passes thro'(5,-3) hence x = 5 is the equation

To graph it plot (5,-3) , (5,1) and so on any point with x = 5

Here is the graph of x = 5
graph{(0.001y-x+5)=0 [-10, 10, -5, 5]}
