About this worksheet

What students practice

Students interpret both coordinates of points on proportional graphs in context.
Students explain the meanings of (0, 0) and (1, r) using labeled axes.
Students distinguish a unit-rate point from other points on a proportional graph.

How to use

Have students label the units of each coordinate before answering. Use the final explanation to discuss how reversing axes changes the unit rate.

Curriculum

Weekend Bike Repair: Reading the Graphs

Connect graph coordinates to charges, services, and work time.

Tire Inflation Charges

Use the graph for questions 1–5. Read the axis labels before interpreting a point.

Amira and Luis run a weekend bike-repair business. They charge the same amount for each tire they inflate, with no extra fee. The connected points show their proportional pricing model; actual tire counts are whole numbers.
