Ivy graphs how much money she earns for hours of babysitting. She finds that the data tends to be linear and draws a line that passes through the points (2, 13) and (5, 32.50) About how much does Ivy earn per hour?

A $5
B $6.50
C $13
D $32.50

B $6.50

Step-by-step explanation:

We need to find the slope

This is given by

m = (y2-y1)/(x2-x1)

   =(32.5 - 13)/(5-2)

   =19.5/3

   = 6.5

square root of 36/6 = 2.449489743

square root of 16/6 = 1.632993162

square root of 6 = 2.449489743

the answer is square root of 16/6 because the square root of 36/6 is the same answer as square root of 6 = 2.449489743
