Constant Rates Revisited

EngageNY 45 min(s)

Students know that any constant rate problem can be described by a linear equation in two variables where the slope of the graph is the constant rate. Students compare two different proportional relationships represented by graphs, equations, and tables to determine which has a greater rate of change. She walks at a constant speed of 3 miles per hour. Work in pairs to express this situation as an equation, a table of values, and a graph.
