A graph which best models a linear function fitted to the average cost of electricity (data) in the scatter plot is shown in the image attached below.
A linear function can be defined as a type of function with an algebraic equation of the first order that has two (2) variables, with each of its term having an exponent of one.
In Mathematics, the resulting points of a scatter plot shows any association (correlation) between the data plotted on the graph.
Based on the average cost of electricity, a graph which best models a linear function fitted to the data in the scatter plot is shown in the image attached below.
