Graph the tracking signals for each products. Instructions: 1. Use the line tool (TS1, TS2, TS3) to draw the tracking signals for each products. 2. To earn full credit for this graph you must plot all required points, beginning with the first unit. 3. To enter exact coordinates, double click on the point and enter the values of x and y
