Question

(-5, 10) (-5, 9) What is the slope?

Answer 1

undefined

Explanation:

Ok, we will use the formula:

`(y^(2) -y^(1) )/(x^(2) -x^(1) )`

The points (-5, 10) is our one, making -5 x1 and 10 y1

The points (-5, 9) is our two, making -5 x2 and 9 y2

now we add them into our formula

`(9-10)/(-5-(-5)) = (-1)/(0)` = undefined

Hope this helps. Check with someone else to make sure. <3

Answer 2

The slope is undefined.

Explanation:

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

m=(9-10)/(-5-(-5))

m=-1/(-5+5)

m=-1/0

undefined

Since the slope is undefined, this is a vertical line.
