Hey, how do you know in a random question with 2 coordinates which is the x1 and y1 and which is the x2 and y2? I keep doing the x1/x2 and y1/y2 the wrong way round!
eh if i am not wrong by what my math teacher taught me any of the two coordinate x can be x1 or x2 and the same for y1 and y2.
if you get a negative just use the fomula shown in the video which needs to square them so they would be positive, althought your comment is 5 months ago hope you get your ans by my comment=) good luck

This is a GMAT Question??.. but it reminds me of grade 10 math.
