he graph below represents the price of sending video messages using the services of a phone company. What is the constant of proportionality? A graph is shown. The values on the x axis are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10. The values on the y axis are 0, 24, 48, 72, 96, 120, 144, 168, 192, 216, 240. Points are shown on ordered pairs 0, 0 and 2, 48 and 4, 96 and 6, 144 and 8, 192. These points are connected by a line. The label on the x axis is Video Messages Sent. The label on the y axis is Price in cents. 12 24 46 48

Answer:

24.

Step-by-step explanation:

Basically constant of proportionality is a ratio.

We take two points, we'll take the order pair (2,48)

It will always be y/x so y is 48 and x is 2

48/2    -  now we simplify

answer: 24

hope this helps! :))
