The airport at Khartoum in Sudan is under attack. The United Nations is trying to evacuate refugees by plane, but it is quite unsafe because of the constant shellfire. The UN troops monitor the shellfire and plot the path that the shells trace. They find out that all of the shells fly along the same path from East to West towards the control tower. They work out that the equation of the path is: h = 0.002d (1200 - d) Where h = height, d = distance east of the control tower. The control tower is at (0, 0) Create the line on GeoGebra using the input bar 1. Describe what the line is like compared to linear equations. Answer the following questions; 2. What position are the shells fired from? 3. Where do they land? 4. What is the greatest height that the shells reach?
