Atsie (atsie):
Find the value of r so that the line that passes through (r,-5) and (3, 13) has a slope of 8. I thought it was -18/5, but now I'm rethinking it because if the slope is 8 then what is r ? Am I correct, or am I wrong?

how did you get -18/5 what formula do you have for finding slope?
Atsie (atsie):
I have \[M = y2 - y1 / x2 - x1 \] as the formula for finding slope. Maybe it'd look better, if I put it like this. |dw:1466519767886:dw|
