question 2

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

question3

the graph below shows the numbers of cups of peach juice that are mixed with different numbers of cups of lemon-lime soda to make servings of peach soda:

a graph is shown. the values on the x axis are 0, 1, 2, 3, 4, 5. the values on the y axis are 0, 9, 18, 27, 36, 45. points are shown on ordered pairs 0, 0 and 1, 9 and 2, 18 and 3, 27 and 4, 36. these points are connected by a line. the label on the x axis is lemon lime soda in cups. the title on the y axis is peach juice in cups.
