Question

Find the slope of the line passing through (-8, 10) and (-8, -7).

Answer 1

• (-8,10)
• (-8,-7)

Slope:-

$\\ \rm\dashrightarrow m=\dfrac{-7-10}{-8+8}$

$\\ \rm\dashrightarrow m=\dfrac{-17}{0}$

$\\ \rm\dashrightarrow m=\infty$

Answer 2

$\frac{y2 - y1}{ x 2 - x1} \\ \frac{ - 7 - 10}{ - 8 + 8} \\ \frac{ - 17}{0}$

Slope is undefined
