 Gradient of horizontal and vertical lines

Interactive practice questions

Which of the following statements is correct for vertical lines?

A vertical line's slope is very large because it is so steep

A

A vertical line has a slope that is undefined because, when calculating the slope using the formula $\frac{\text{rise }}{\text{run }}$rise run , the run is $0$0 and it is not possible to divide a number by $0$0

B

A vertical line's slope is equal to $0$0 because when calculating the slope using the formula $\frac{\text{rise }}{\text{run }}$rise run , the run is $0$0
