Gradient of Horizontal and Vertical Lines

Interactive practice questions

Which of the following statements is correct for vertical lines?

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

A

A vertical line has a gradient that is undefined because, when calculating the gradient 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 gradient is equal to $0$0 because when calculating the gradient using the formula $\frac{\text{rise }}{\text{run }}$rise run , the run is $0$0
