Ok so I have an assignment for my Calculas/Geometry class and I seem to have not paid the greatest attention in class as I'm pretty much completely lost. I was wondering if anyone could help me with one of the questions. The first part asked for a diagram which satified the following X divides YZ in a ration of -5:7 and also that T divides XY in the ratio 1:3. (I'm pretty sure I have correctly completed this part) The next part states that if O is not on the line, write OT as a linear combination of OX and OY. Also it says to write OY as a linear combination of OT and OZ.
