Plane A has just 1 ton of fuel left and has requested plane B to refuel it. Plane B has 21 tons of fuel. Fuel transfer happens at the rate of 1 ton per minute. Use this information as you work through the activity and find how long it will take to refuel plane A until both planes have the same amount of fuel. Let x be the time in minutes and y be the amount of fuel in tons. The equation y = x + 1 represents the quantity of fuel with respect to time in plane A, and y = -x + 21 represents the quantity of fuel with respect to time in plane B. For each equation, find two points that satisfy the equation. Later, you’ll use these points to graph the lines of the equations.
