Answer 1

Taking two of the exact points:

`\begin{gathered} (x1,y1)=(2,50) \\ (x2,y2)=(6,80) \\ m=(y2-y1)/(x2-x1)=(80-50)/(6-2)=(30)/(4)=7.5 \\ \end{gathered}`

From the graph we can also conclude that the y-intercept could be 45, therefore the function which best models that data is:

`y=6.52x+45`
