First, find 2 numbers that multiply to 56 and add to -15 (-8,-7)
therefore, the factored version is (n-7) (n-8)
:)
Slope = rise/run
So we can let the rise be -1, and the run be 5
So take the point (1,4)
"Rise" it by -1 (lower it by 1): (1,3)
Run by 5 (move to the right by 5): (6,3)
Now take these two points (1,4) and (6,3) and draw a line connecting them.
