= 3.60
Solution:
We have the equation:
14.4 ÷ 4 = 3.60
Calculated to 2 decimal places.
Point a is at (-2,4) => (x1,y1)
Midpoint is (2.5, 3.5) => (a,b)
Point B is (x2, y2)
To find midpoint we use formula

a= 2.5, b= 3.5, x1= -2 and y1= 4
Plug in all the values and findout x2, y2

multiply 2 on both sides to remove fraction
(5 = -2+x2 , 7 = 4+ y2)
5 = -2+x2, so x2= 7
7 = 4+ y2, so y2= 3
The point B is ( 7, 3)
Start at (0, 72), then (1, 64), (2, 56), ETC. I hope you see the pattern! Do it until you reach (9, 0)
