Create a table of values from the graph. Then find the value of y when x=20. Use pencil and paper. Find three more pairs of values. Then write a situation you could model using this graph.
x y
2 blank
blank 3.25
blank 4
6 blank
x y
2 2.75
8 3.25
10 4
6 3.5
In this situation, the x-values represent the number of hours spent studying and the y-values represent the corresponding test scores.
