The relationship between the cost and the miles driven, as presented on the graph is an illustration of a linear equation or a linear graph.
- The growth rate per year is $0.36 per year
- The cost of owning and operating the car is $7201.44
<u>A. The growth per year</u>
This simply means that we calculate the slope (m) of the graph.
This is calculated using:
From the graph, we have:
So, we have:
Hence, the growth per year is: $0.36 per year
<u>B. The cost, when the number of miles is 20004 miles</u>
The equation of a straight line is:
Where:
--- the slope
--- the point where the graph crosses the y-axis.
So, we have:
The cost when the miles driven is 20004, is:
The cost of owning and operating the car is $7201.44
