Question

Find the slope between the two points: (-7, 4) and (-7, 9)

Answer 1

slope is undefined

Explanation:

calculate the slope m using the slope formula

m =
`(y_(2)-y_(1) )/(x_(2)-x_(1) )`

with (x₁, y₁ ) = (- 7, 4 ) and (x₂, y₂ ) = (- 7, 9 )

m =
`(9-4)/(-7-(-7))` =
`(5)/(-7+7)` =
`(5)/(0)`

division by zero is undefined thus the slope is undefined
