Figure 4

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

  1. A 4 quadrant coordinate graph with a line going through the points (negative 1, comma 5) and (2, comma negative 1).

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

    Growth rate:

  1.   

What is the difference between each -value?
What is the value of when is ?

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