The graph below shows the prices of different numbers of boots at a store:

A graph is shown. The values on the x axis are 0, 2, 4, 6, 8, and 10. The values on the y axis are 0, 25, 50, 75, 100, and 125. Points are shown on ordered pairs 0, 0 and 2, 25 and 4, 50 and 6, 75 and 8, 100. These points are connected by a line. The label on the x axis is Number of Boots. The title on the y axis is Price in dollars.

Which equation can be used to determine p, the cost of b boots?

p = 12.50b
p = 25b
b = 25p
b = 12.50p
