Question

example 1: gas mileage
in 2007, the most fuel-efficient mid - sized car for city driving was the toyota prius, which was rated at 60 miles per gallon. the least efficient mid - sized car for city driving was the ferrari 612 scaglietti, rated at 10 miles per gallon. (www.fueleconomy.gov)
in the table, each row of data represents an ordered pair. plot the data using two different colors (one for each type of car) and then draw a straight line through each set of plotted points.

$$\begin{tabular}{c|c}gallons&miles\\hline1&60\\hline2&120\\hline3&180\\hline4&240\\end{tabular}$$

\

$$\begin{tabular}{c|c}gallons&miles\\hline2&20\\hline4&40\\hline6&60\\hline8&80\\end{tabular}$$

Explanation:

Step1: Plot Toyota Prius points

For Toyota Prius, the ordered pairs are \((1,60)\), \((2,120)\), \((3,180)\), \((4,240)\). On the graph, for \(x = 1\) (gallons), \(y=60\) (miles); for \(x = 2\), \(y = 120\); for \(x=3\), \(y = 180\); for \(x = 4\), \(y=240\). Mark these points.

Step2: Plot Ferrari 612 points

For Ferrari 612, the ordered pairs are \((2,20)\), \((4,40)\), \((6,60)\), \((8,80)\). On the graph, for \(x = 2\) (gallons), \(y = 20\) (miles); for \(x=4\), \(y = 40\); for \(x = 6\), \(y=60\); for \(x = 8\), \(y = 80\). Mark these points with a different color.

Step3: Draw lines

Draw a straight line through the Toyota Prius points and another straight line through the Ferrari 612 points.

Answer:

The graph with Toyota Prius points \((1,60)\), \((2,120)\), \((3,180)\), \((4,240)\) plotted and connected by a line, and Ferrari 612 points \((2,20)\), \((4,40)\), \((6,60)\), \((8,80)\) plotted and connected by a line (using two different colors as per instruction).
