Question

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

Answer 1

`(y2 - y1)/( x 2 - x1) \\ ( - 7 - 10)/( - 8 + 8) \\ ( - 17)/(0)`

Slope is undefined

Answer 2

• (-8,10)
• (-8,-7)

Slope:-

`\\ \rm\dashrightarrow m=(-7-10)/(-8+8)`

`\\ \rm\dashrightarrow m=(-17)/(0)`

`\\ \rm\dashrightarrow m=\infty`
