The Problem Set Guidance describes a possible activity to help students make connections between the representations. This is a good opportunity for students to showcase their collective work and look at the work of others, via posters, a gallery walk, or in small groups.
If you need to adapt or shorten this lesson for remote learning, we suggest prioritizing Anchor Problem 1 (benefits from discussion). Find more guidance on adapting our math curriculum for remote learning here.

A proportional relationship is shown in the graph below.
Jonathan and his brother Jeffrey went on a long run to prepare for an upcoming road race. Jonathan ran 18 miles in 4 hours. It took Jeffrey 6 hours to run the same route as his brother. Both brothers ran at a constant speed.

Patrice makes a spicy salsa by adding red pepper flakes to a chunky tomato mix in proportional amounts. For example, she mixes $$\frac{1}{2}$$ teaspoon of red pepper flakes to 2 cups of tomato mix.
Represent the relationship between red pepper flakes, in teaspoons, to tomato mix, in cups, in two different ways (table, graph, or equation). In your work, define any variables that you use.
