Kayak Rental Cost and Graphing

The video tutorial guides sixth graders through writing and graphing an equation in two variables. Using the example of renting a kayak, the teacher explains how to define variables for total cost and hours rented. The equation is built as C = 25 + 8H, where C is the total cost and H is the hours rented. A data table is created to generate ordered pairs, which are then graphed. The graph shows the relationship between hours rented and total cost, illustrating how the cost increases by $8 per hour.

What is the main topic of the lesson?

• Learning about historical events

• Understanding fractions

• Writing and graphing an equation in two variables

• Solving quadratic equations

What does the variable 'C' represent in the equation?

• The speed of the kayak

• The number of hours

• The total cost of renting a kayak

• The number of kayaks

What is the second variable defined in the lesson?

• The number of kayaks

• The total cost

• The distance traveled

• The number of hours the kayak is rented

How is the equation for the total cost of renting a kayak structured?

• C = 25H + 8

• C = 8 + 25H

• C = 25 + 8H

• C = 8H + 25
