Question

The graph below shows the price of different numbers of hats at a store:

A graph is shown. The values on the x-axis are 0, 2, 4, 6, 8, 10. The values on the y-axis are 0, 13, 26, 39, 52, and 65. Points are shown on ordered pairs 0, 0 and 2, 13 and 4, 26 and 6, 39 and 8, 52. These points are connected by a line. The label on the x-axis is Number of Hats. The title on the y-axis is Price in dollars.
Which equation can be used to determine p, the cost of h hats? (1 point)


h = 6.50p

p = 13h

p = 6.50h

h = 13p

Answer 1

p=6.50h yeah ur welcome

Answer 2

Since p is the cost of h hats, the output is the p and the input is h.
p=?h

Now we find the slope by using m=(y2-y1)/(x2-x1) and points (2,13), (4,26)
m=(26-13)/(4-2)=13/2=6.5

OR using the proportionality constant since y is a direct variation to x
K=y/x=13/2=6.5

Solution: p=6.5h
