Can someone do these two for me please?

Answer:
3) 2
4) Water's Edge Rafts
Step-by-step explanation:
3) Rate of change is nothing but the slope
Slope formula : y2 - y1 / x2 - x1
13 - 11 / 2 - 1
2/1
2
Rate of change = 2
4) Rate of change : y2 - y1 / x2 - x1
Water's Edge Rafts
36 - 6 / 6 - 1
30/5
6
Water's Edge Rafts' Rate of change = 6
Ryan's Rafts
17.25 - 15.00 / 2 - 1
2.25/1
2.25
Ryan's Rafts' Rate of change = 2.25
6>2.25
So, Water's Edge Rafts' has the highest rate of change
