I think you multiply 1/2 by the x and y point
1/2(0)= 0
1/2(-6)= -3
(0,-3)
685-85=600
1 year =12 months
12 multiply by 2 =24
600 divided by 24=25
answer=25
Divide each term in the y column by 2 to go from this list {8, 2, 0, 2, 8} to this list {4, 1, 0, 1, 4}
This list {4, 1, 0, 1, 4} is a bunch of perfect squares so it suggests that y = x^2
However we must double the values to get back to the original list. So the rule is y = 2*x^2
3.33=333%
and
3/5=.6=60%
to find a percent find a decimal and move the decimal point two spaces right
