what is the slope of (-6,8) (-6,3)

Answer 1

Hello, thank you for taking the time to post your question!

The equation that you want to use to compute slope here is

m = (y2 – y1) / (x2 – x1) … for this set of values that becomes

m = (3 - 8) / (-6 – -6) = -5 / 0 , meaning that the slope for this set of points is undefined because it’s not possible to divide by 0

I hope that helps you get moving in a better direction on this type of question! Feel free to reach out if you have any additional questions beyond that :)

Answer 2

the slope euation is m = (y2 - y1) / (x2 - x1)

where m is slope, (x1,y1) is your first set of coordinates and (x2,y2) are your second set of coordinates.

Plug in your numbers: m = (3 - 8) / (-6 - (-6)) <=> (-5) / (-6 + 6) <=> (-5) / (0) <=> -5/0 = Undefined

therefore the slope "m" is undefined.

Simply put, slope has to have a horizontal element (x,y) where x≠0. If the slope is a vertical line, then it is undefined because it doesn't have the horizontal element. Similarly, if the slope is a horizontal line, then it is 0 since it doesn't travel any vertical distance.
