(a)

To determine

Construct scatter diagram for $\left(x,y\right)$ data pairs.

Identify whether the straight line would be a good fit for data or not.

Explain whether the y values seem almost to explode as time goes on or not.

(b)

To determine

Construct scatter diagram for $\left(x,y\text{'}\right)$ data pairs.
