To determine the rate of a number do the following steps:
Multiply the number by the percent (e.g. 87 * 68 = 5916)
Divide the answer by 100 (Move decimal point two places to the left) (e.g. 5916/100 = 59.16)
Round to the desired precision (e.g. 59.16 rounded to the nearest whole number = 59)

x^2=x+12
x=-3
x=4
y=-3+12
y=4+12
y=9
y=16
(x1,y1)=(-3,9)
(x2,y2)=(4,16)
