Slope of (-4, 1) and (2, 1)

Check explanation

Step-by-step explanation:

I think that you might be missing a negative in one of your values because it comes out to 0 if you put both y's as 1 ...

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

m = (1 - 1) / (2 - (-4))

m = 0 / 6

m = 0

but if one of the ones is negative then it would be

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

m = (1 - (-1)) / (2 - (-4))

m = 2 / 6

m = 1 / 3
