SOLUTION

To get the unit rate here, you can just pick any two points and get the slope. The slope becomes the unit rate.

Let's pick the points (0.2, 1.5) and (0.7, 5)

The slope becomes


\begin{gathered} m=(y_2-y_1)/(x_2-x_1) \\ m\text{ = slope and } \\ x_1=0.2,y_1=1.5,x_2=0.7,y_2=5 \end{gathered}

slope becomes


\begin{gathered} m=(y_2-y_1)/(x_2-x_1) \\ m=\frac{5-1.5_{}}{0.7_{}-0.2_{}} \\ m=(3.5)/(0.5) \\ m=7 \end{gathered}

Hence, the unit rate = 7.0
