The equation that satisfies the information provided is y=2.75x, therefore the coordinates to plot on your graph are as follows.
(1,2.75)
(6,16.50)
(10, 27.5)
(20,55)
(30,82.5)
(40,110)
The graph accordingly, can’t really get the whole graph in but hopefully you get the idea and you can use the coordinates above :)
