2-74.

Each part below represents a different situation. For each situation, determine the pattern of growth and the number of tiles in Figure 0 or the y-intercept. Homework Help ✎

a.

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

b.

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

• Growth rate: −2

c. $y=3x−14$

• G = 3, y-int = –14

d.

 x –3 –2 –1 0 1 2 3 y 18 13 8 3 –2 –7 –12

• What is the difference between each y-value?
What is the value of y when x is 0?

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