Question

Find slope of the line (7,7) and (7,-5)

Answer 1

slope is undefined

Explanation:

Calculate the slope m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (7, 7) and (x₂, y₂ ) = (7, - 5)

m =
`(-5-7)/(7-7)` =
`(-12)/(0)`

Division by zero is undefined, hence slope of line is undefined
