Does the following table represent a proportional relationship? If so identify the constant of proportional and create an equation to represent it.

• Proportional; k = 1/40 pages per day; y=1/40x

• Proportional; k = 40 pages per day; y=40x

• Not Proportional

• Proportional; k = 40 days per pages; y=40x
