To paint a house, a painting company charges a flat rate of $500 for supplies, plus $50 for each hour of labor.

How much would the painting company charge to paint a house that needs 20 hours of labor? A house that needs 50 hours?

Draw a line representing the relationship between x, the number of hours it takes the painting company to finish the house, and y, the total cost of painting the house. Label the two points from the earlier question on your graph.

Find the slope of the line. What is the meaning of the slope in this context?

Tyler and Elena are on the cross country team.

Tyler's distances and times for a training run are shown on the graph.
