About this worksheet

What students practice

Students interpret both coordinates of points on proportional graphs in context.
Students explain the meanings of the origin and unit-rate points using labeled axes.
Students use proportional graph points to evaluate project-progress plans.

How to use

Have students read each graph's axis labels before answering. Use the final explanation to discuss when a proportional progress model stops applying.

Curriculum

Common Core standard covered

7.RP.A.2.d

Explain what a point (x, y) on a proportional graph means in context, especially (0, 0) and (1, r) where r is the unit rate.

Coding Camp: Annotate the Progress Graphs

Connect graph coordinates to project progress and unit rates.

Testing Dashboard

Use the testing graph for Questions 1–5. The camp models testing at a constant rate. Hours count active testing time only, not breaks.

Select the two dashboard labels that correctly describe point V.

6 scripts tested after 3 active testing hours3 scripts tested after 6 active testing hours3 active testing hours paired with 6 scripts tested6 scripts tested during each active testing hour

The dashboard highlights U rather than W to display the unit rate directly. Why?

A. U represents the total number of scripts in the project.
B. U represents exactly one hour of active testing.
C. U represents the first script tested during camp.
D. U represents fewer tested scripts than W does.

A progress alert should appear when 8 scripts have been tested. Use the graph's coordinate order.

What x-coordinate belongs in the alert point ( , 8)?

Before testing begins, Hana has already written 10 scripts. Which note correctly explains O on this testing graph?

A. Ten scripts have been tested, and no testing time remains.
B. No testing time has been used, and no scripts have been written.
C. No testing time has been used, and no scripts have been tested.
D. Ten testing hours remain, and no scripts have been tested.

At V, Hana takes a 30-minute break without testing any scripts. The dashboard still uses active testing hours. Which point should it show immediately after the break?

A. It should show (0, 0), restarting the testing record.
B. It should show (3.5, 6), counting the break as testing time.
C. It should show (3, 6), keeping both recorded totals.
D. It should show (3.5, 7), extending the testing model.

Module Planning

Use the module graph for Questions 6–10. It models the active work time needed to complete equal-sized coding modules at a constant rate. Partial module progress is allowed.

Which heading correctly describes the unit rate r in the point (1, r) on this graph?

A. Active work hours needed per module
B. Active work hours remaining at camp
C. Modules completed per active work hour
D. Modules remaining after one work hour

A planning tool needs the point that gives the time for exactly one module. Use a decimal.

Complete the point: (1, ). This y-coordinate is measured in hours.

Malik has a 90-minute work session. Since 90 minutes is 1.5 hours, which graph point describes his modeled progress?

A. The point (1, 1.5) represents 1 module in 1.5 hours.
B. The point (1.5, 2) represents 1.5 modules in 2 hours.
C. The point (2, 3) represents 2 modules in 3 hours.
D. The point (2, 1.5) represents 2 modules in 1.5 hours.

A teammate calls K's y-coordinate, 3, the time per module. Select the two notes that correct this mistake.

The 3 hours are paired with 4 modules, not 1 module.The time per module is 4 ÷ 3 hours.The time per module is 3 ÷ 4 hours.A labeled point cannot be used to find a unit rate.

10.

A team plans to complete 6 modules. Its planning note uses the point (6, y) on this graph.

How many active work hours does the y-coordinate represent? hours

Review the Project Notes

Read the axis meanings carefully. Use the proportional models only for the quantities they describe.

11.

A file-upload graph uses x = active upload time in minutes and y = data uploaded in megabytes. Its unit-rate point is (1, 6). A status message says, “At (2.5, 15), the upload has run for 15 minutes.” Which replacement is correct?

A. The upload has sent 15 megabytes in 2.5 minutes.
B. The upload has sent 2.5 megabytes in 15 minutes.
C. The upload has sent 15 megabytes in each minute.
D. The upload has sent 6 megabytes in 2.5 minutes.

12.

A debugging model uses x = hours worked and y = bugs fixed. A documentation model uses x = hours worked and y = pages finished. Both contain (1, 3). Which conclusion respects the meanings of both points?

A. One debugging hour fixes 3 pages; one documentation hour finishes 3 bugs.
B. One debugging hour fixes 3 bugs; one documentation hour finishes 3 pages.
C. One bug takes 3 debugging hours; one page takes 3 documentation hours.
D. Three debugging hours fix 1 bug; three documentation hours finish 1 page.

13.

A camp project has exactly 12 features to complete. A proportional planning graph uses x = active work hours and y = features completed. It contains (0, 0), (1, 3), and (4, 12). Tessa says, “The next point must be (5, 15), so we will complete 15 features in this project.” Explain what (1, 3) means and why Tessa's project claim does not follow.
