Question

What is the slope of the line that passes through the points ( 9 , 2 ) (9,2) and ( 9 , 27 ) (9,27)? write your answer in simplest form.

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 ) = (9, 2 ) and (x₂, y₂ ) = (9, 27 )

m =
`(27-2)/(9-9)` =
`(25)/(0)`

division by zero is undefined then slope of line is undefined
