Find the slope of the line that
passes through (-9,-6) and (-9, -10)
-9

Undefined

Step-by-step explanation:

(see attached for reference)

in our case, we are given 2 points

(x₁, y₁) = (-9,-6)

(x₂, y₂) = (-9,-10)

immediately we can see that the x-ordinate for both points are the same, which means that if we were to draw a line through both points, it would form a vertical line.

By definition, a vertical line has a slope that is undefined (answer)

i just took the test, the correct answer is .. 31.5 in.
