Okay, so you’re finding the slope so
mx+b
You’ll take the y coordinate 2 and subtract it from y coordinate 1
Then you’ll take x coordinate 2 and subtract it from x coordinate 1
You’ll get -6 -0 for the y coordinates and you’ll get 0- -8 for x coordinates you put -6 over 8 like a fraction so -6/8 simply and get - 3/4
