1. Make a graph that represents this data.

2. Find the equation of the line between the points (0, 250) and (30, 550).

3. What does the slope of the line represent?

4. Which is the independent variable?; Which is the dependent variable?

Example Tom the Cat decides to rent his catnip to his brother. He charges

a 75 cent deposit and 25 cents per day (paid upfront).
