Question

Slope for (-5, 9) and (-5, -5)

Answer 1

It’s perpendicular

Explanation:

Answer 2

Answer:
`m=`∞

Explanation:

The formula for calculating slope is given as:

`m = (y_(2)-y_(1))/(x_(2)-x_(1))`

`x_(1)=-5`

`x_(2)=-5`

`y_(1)=9`

`y_(2)=-5`

substituting into the formula , we have

`m = (-5-9)/(-5-(-5))`

`m = (-14)/(-5+5)`

`m = (-14)/(0)`

Therefore :

`m=`∞
