About this worksheet

What students practice

  • Students graph proportional relationships and interpret slope as a unit rate.
  • Students compare proportional relationships represented by graphs, tables, equations, and descriptions.
  • Students use proportional rates to make repair scheduling and supply purchasing decisions.

How to use

Use after introducing proportional graphs. Have students label graph axes, include units in rate comparisons, and explain the final plotting error.

Curriculum

Common Core standard covered

8.EE.B.5

Graph proportional relationships, read the unit rate as the slope, and compare two proportional relationships shown in different ways.

  • B. (0, 0), (4, 3), (8, 3)
  • C. (0, 0), (4, 4), (8, 8)
  • D. (0, 0), (4, 3), (8, 6)
2.
Use the tune-up graph in Question 1. Mina reserves 4.5 working hours for tune-ups.

How many bikes does the model allow her to schedule?   bikes
