    The ending point i came up with was 6, 1. So if the starting point was 1, -2, would i subtract the coordinates? Thats were I got lost

    Yes. Start point was 1,-2 and the end point was 6, 1

    awesome. now how many blocks in the y direction (south direction) do we need to reach the same horizontal line as where its starting point was?

    I have a feeling the answer is 5, -3 unless my mathmatical skills just suck

    did you go 3blocks up from the end point, or 3 blocks down from the end point?

    going up we always take positive steps, and going down we take negative steps.

    its like a vertical number line!

    Correct. And 5 units west on the x line or whatever to get back to the starting point. So sense it goes "west" it would be a negative outcome, correct?

    well to confirm your thoughts, if i had a number line, and i started at 1, how do you end up at 0. we subtract 1 right? hence we go -1 units. so yes, for this example, we will go -3 units in the y direction and -5 units in the x direction
