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 = (9 - 1) / (-1 - -3) = 8/ 2 = 4

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

(-3, 2) and (-1, 9)

m = (change in y)/(change in x) = (9-2)/[(-1-(-3)] = 7/2

 

(–3, 1) and (–1, 9)

m = (9-1)/(-1-(-3)) = 8/2 = 4
