Name 5.5 Writing Linear Equations. Renting A Canoe Costs

Name __________________________________________ 5.5 Writing Linear Equations. Renting a canoe costs $10 plus $28 per day. The linear model for this situation relates the total cost of renting a canoe, y, with the number of days rented, x. 1. What number corresponds to the slope in the linear model?_________ 2. What number corresponds to the y – intercept in the linear model? ______________ 3. Use the slope y-intercept form to write the linear model.______________________ 4. Use the linear model to find the cost of renting a canoe for 3 days.

5. If you had $66 to spend, for how many days could you rent a canoe?

A family is going on a trip that is 1500 miles long. That family travel starts at home at t = 0 and travels at a constant rate of 67.5 miles per hour. 6. What number corresponds to the slope in the linear model?_________ 7. What number corresponds to the y – intercept in the linear model? ______________ 8. Use the slope y-intercept form to write the linear model.______________________ 9. After 19 ½ hours has the family reached their destination?

10. Use the equation you wrote to determine the time it will take the family to reach their destination.

Determine whether the table of values represents a linear relationship, if so; write the equation for the line. 11. x y
