The graph below represents the price of sending picture 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, 22, 44, 66, 88, 110, 132, 154, 176, 198, 220. Points are shown on ordered pairs 0, 0 and 2, 44 and 4, 88 and 6, 132 and 8, 176. These points are connected by a line. The label on the x axis is Picture Messages Sent. The label on the y axis is Price in cents. 10 11 21 22

    The constant of proportionality is equal to the slope in this case

    use the slope formula \[\Large m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}\]

    (x1,y1) = (0,0) (x2,y2) = (2,44) \[\Large m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}\] \[\Large m = \frac{44-0}{2-0}\] \[\Large m = ???\]

    the slope is 22 so the constant of proportionality is 22
