This graph shows the linear relationship between the number of miles (m) by the number of hours (h).

Find the constant of proportionality (r). Using the value for r, enter an equation in the form of m = rh that represents the relationship between the number of miles (m) and the number of hours (h).

• 120 = 2*60

• m = 60h

• m = 60

• 300 = 5*60

Write an equation for this relationship.

• y=1/5x
• y=1/2x
• y=2x
• y=5x
