How many more squares does Figure 3 have than Figure 2?

Make a slope triangle between two points on the graph to find the slope, or the growth rate.

Growth rate:

What is the difference between each -value?

What is the value of

*is*

Which situation above is growing (increasing) at the fastest rate?
