Did you drive to work or school today? When you are driving at aconstant speed, the amount of gas left in the tank can typically bemodeled by a linear equation. The equation y = -2x + 15 wouldrepresent a car that has a full 15-gallon tank and burns 2 gallonsof gas an hour when x is the number of hours driven and y is theamount of gas in the tank. Find a linear relationship (equation)that you would use or rely on in your field when you receive yourdegree, and explain what it is and how it is used. Identify theinitial condition, such as the full tank of gas above, and the rateof change. For a linear equation, the rate of change (slope) needsto be constant. If you can’t find one in your field, broaden yourresearch to include any real-world application.
