563/.4 is equal to 1,407.5
(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)
Area is proportional to the square of the dimensions.
Divide the dimensions by 3, and you divide the area by 3-squared = 9.
