A builder is trying to level out some ground with a front-end loader. He picks up some excess dirt at 9,16 and then maneuvers through the job site along the vectors 〈-6,0〉, 〈2,5〉, and 〈8,10〉 to get to the spot to unload the dirt. Find the coordinates of the unloading point and find a single vector from the loading point to the unloading point.
