The scatter graph shows the oil production P and carbon dioxide emissions C for various years since

Question:

The scatter graph shows the oil production P and carbon dioxide emissions C for various years since 1970. A line of best fit has been added to the scatter graph.

a. Use two points on the line to calculate its gradient.

b. Formulate a linear model linking oil production P and carbon dioxide emissions C, giving the relationship in the form C = aP + b.

c. Interpret the value of a in your model.

d. With reference to your value of b, comment on the validity of the model for small values of P.
