2.

We have two stacks of styrofoam cups.
One stack has 6 cups, and its height is 15 cm.
The other stack has 12 cups, and its height is 23 cm.
How many cups are needed for a stack with a height of 50 cm?

5.3: Connecting Slope to Rate of Change

Create a graph of how to determine the number of cups needed to be stacked to reach 50cm.
