Question

80 POINTS!

The graph below shows the prices of different numbers of sunglasses 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, 9, 18, 27, 36, and 45. Points are shown on ordered pairs 0, 0 and 2, 9 and 4, 18 and 6, 27 and 8, 36. These points are connected by a line. The label on the x axis is Number of Sunglasses. The title on the y axis is Price in dollars.

Which equation can be used to determine p, the cost of s sunglasses?

p = 4.50 + s
p = 4.50s
s = 4.50 + p
s = 4.50p

Answer 1

B. 4.50s

Explanation:

I took the segment exam and got it right!

Answer 2

p = 4.50s

Explanation:

slope = (y2-y1)/(x2-x1)

slope = (36-0)/(8-0)

slope = 36/8

slope = 9/2

slope = 4.5

the y intercept = 0

slope intercept form of the equation is

y = mx+b

y = 4.5 x +0

p = price of the sunglasses or y

x = number of sunglasses or s

p = 4.5 s
