    No the question issnt asking for ordered pairs. It's a line with points so it'll be like|dw:1379387454390:dw|

    I thought when you wrote out A -1,321 you meant (-1,321) or something

    the distance from A -1,321 and B 517 on the number line is found by subtracting 517 - ( -1321) 517 + 1321 1838

    add the two values, then divide by 2 to get the midpoint

    since -421 is a much bigger number in the negative direction
