Question

Calculate the slope of the line passing through points (-3, 4) and (-3,-7)

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 ) = (- 3, 4 ) and (x₂, y₂ ) = (- 3, - 7 )

m =
`(-7-4)/(-3+3)` =
`(-11)/(0)`

Since division by zero is undefined then the slope is undefined

This indicates the line is vertical and parallel to the y- axis
