Answer:

Step-by-step explanation:

1.

a. m = (y2-y1)/(x2-x1) = slope

Function 1:

m = (9-4)/(-3+1)

m = -5/2

Function 2:

m = (4-0)/(0+1)

m = 4/1

b. Function 2 has the greater rate of change.

2.

a.

g = 6-2w

g = 6.75-3w

b and c.

If you graph both of those functions they will cross each other and where they cross is the price of each item. The w value will be the waffle at $0.75 and the g value will be the grand slam at $4.50.
