Question

What is the slope, m, of the line through (-9, -17) and (-9, 12)?

Express the slope as a fraction in lowest terms.

If the slope is undefined, enter undefined into the text box.

m =

Answer 1

m = undefined

Explanation:

(-9, -17) and (-9, 12)

Slope:

m=(y2-y1)/(x2-x1)

m=(12+17)/(-9+9)

m=29/0

Since 0 is the denominator, the slope is undefined
