Question

What is the slope of the line x = –5?

Answer 1

Does not exist or undefined.

Answer 2

the line x=-5, is all y's where x=-5. so basically it's a vertical line passing through x=-5. Like this:

so what would be the slope? what do you think?

Answer 3

\(y=\dfrac{y_2-y_1}{x_2-x_1}\)

\(x\) does not change so there is a zero in the denominator, therefore the slope does not exist.

Answer 4
