Please help me with this question about vectors. Thanks.
If you are given a graph with a vector starting at the point (1,-1)and the arrow goes to the point (0,-4). What is the vector in rectangular coordinate?
I answered (0,-3), but the coordinate for x is wrong and I can't figure it out.
odd, you could get (-4)-(-1) = -3 for y,
but can't get (0)-(1) = -1 for x...
