Domino Effect
How much does Domino's charge for pizza?
Students will
- Understand the ideas of slope and y-intercept within the context of Domino’s pizza pricing
- Write and graph a linear equation given two points on the line
- Understand what it means for a function to be linear (constant rate of change)
Before you begin
Students should be able to calculate a unit rate (e.g. “cost per topping”). As this lesson is meant to be introductory, no prior knowledge of linear functions is assumed.Common Core Standards
