Question

Find the slope between the following coordinates. (6,4)&(6,-2)​

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 ) = (6, 4 ) and (x₂, y₂ ) = (6, - 2 )

m =
`(-2-4)/(6-6)` =
`(-6)/(0)`

division by zero is undefined, therefore the slope of the vertical line is undefined.
