Activity 5: Linear Equations - Fuel Consumption (GLEs: 10, 11, 13, 14)
CC: Have students research the fuel (natural gas, electricity, gasoline) consumption for various types of furnaces, refrigerators, water heaters, and automobiles. Next, have students write an equation for the fuel consumption. UCEMC- kwh Usage Chart http://www.ucemc.com/kwh%20usage%20chart.htm
CC: Have students use the spreadsheet to plot the (x, y) coordinates from the table on the coordinate plane. If graphing calculators are available, have the students set up a table of values and plot the points to determine if the points fall on a line.
MS Excel may be used for creating the spreadsheet and plotting the points.
This site may also be used to graph the ordered pairs. Choose no line. http://nces.ed.gov/nceskids/graphing/
