(2, 2 1/4) (3, 3 3/8) = (2.25) (3, 3.375)
If it's linear, the line through the points has slope = (3.375-2.25)/(3-2) = 1.125 = 1 1/8
y=1.125x + b, plug in either point to calculate b
2.25 = 1.125(2) + b
b = 2.25 - 2.25 = 0
y=1.125x is a linear equation for two points. Check and see if it works for the other points
(4,4.5)
4.5 = 1.125(4) = 4.5
(5, 5.625) = (5, 5 5/8)
5.625 = 1.125(5) = 5.625
It's a linear relation, not exponential
Plot the points, they all lie on a straight line. "Linear" means graphically a straight line
