Question

The graph below shows the price of different numbers of swim bags 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, 15, 30, 45, 60, and 75. Points are shown on ordered pairs 0, 0 and 2, 15 and 4, 30 and 6, 45 and 8, 60. These points are connected by a line. The label on the x axis is Number of Bags. The title on the y axis is Price in dollars.

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

p = 7.50 + b
b = 7.50 + p
p = 7.50b
b = 7.50p

Answer 4

(0,0), (2,15),(4,30), (6,45),(8,60)
except (0,0) , pick one pair

Answer 5

I thinks its b but im not sure

Answer 6

I don't trust "guessing", I trust logic.
If you want to be sure about the answer, all you need is to find it out by LOGIC, not guess.

Answer 7

Ok can you help me with that please and dont leave the question @Loser66

Answer 8

you need find p, right? hence, the equation for b is nonsense. Get rid them of, you have either a or c
Now a, put the point, (2,15) in p = 7.5 + b ,
Now, d, again put them into the equation p = 7.5 b
