If a number has a decimal that is .5+, you round up. If it is .4-, you round down. So 817.502 would be 818.
She can cut six pieces and will have ¾ of a piece leftover.
(2,-2)(5,7)
7-(-2)= 9
5-2= 3
9/3= 3
slope = 3
(you could also calculate the slope by just counting up how many units it goes up/down when you pick a point from the x-axis and move left/right. basically counting the rise over run)
