Slope Question

Question

What is the slope of the graph of the line x = –1?

Answer 1

Hello, thank you for taking the time to post your question!

x = -1 is a vertical line, which means that the slope here is undefined! that will be true any time you have an equation in the form x = a

I hope that helps you get moving in a better direction on this type of question! Feel free to reach out if you have any additional questions beyond that :)

Answer 2

Pick two points on the line, like (-1,0) and (-1, 5)

m = (y2 - y1)/(x2 - x1)

m= (5 - 0) / (-1 - -1)

m= 5/0

5/0 is undefined, because you can't divide by zero. So the slope of the line is undefined, and the line is vertical.
