About this worksheet

What students practice

Students compare rates of change and initial values of functions represented in different ways.
Students compare function outputs and milestone times in coding-project situations.
Students justify comparisons of linear and nonlinear progress models.

How to use

Use after students have practiced reading linear functions in several forms. Have students annotate rates and starting values, then discuss the final reasoning question.

Curriculum

Compare each pair of models. Each question describes a separate coding-camp task. Assume stated patterns continue over the time being compared.

Noor's completed-task model is linear and is shown in the table. Ellis uses y = 3x + 2. For both models, x is sessions elapsed and y is completed tasks. Which comparison is correct?

Noor's Task Model
Sessions, x	Completed tasks, y
1	7
3	11
5	15

A. Noor starts with more tasks and completes tasks slower.
B. Noor starts with more tasks and completes tasks faster.
C. Noor starts with fewer tasks and completes tasks slower.
D. Noor starts with fewer tasks and completes tasks faster.

Two teams are building pages for their projects. The table shows Cedar's linear model. Maple starts with no completed pages and completes 4 pages per session. Each team needs 20 completed pages.

Cedar's Page Model
Sessions elapsed	Completed pages
0	2
2	8
4	14

How many more sessions does Cedar need than Maple to reach 20 pages? session

The graph shows Priya's linear model for completed screens. Mateo's model is y = 2x + 2. Here x is hours elapsed and y is completed screens. Which comparison is correct?
