How do I know which is right- y2-y1 over x2-x1 or y1-y2 over x1-x2 People say it's the same on yahoo answers but they get different answers a lot. HELP It's different. Let's say (-2,8) and (2,-1). First way: -1 - 8 = -9 2 - (-2) = 0 So... -9/0 Second way: 8- (-1) = 9 -2 - 2 = 0 So... 9/0 See it's like this all the time. In this example they are the same because it is undefined, but in other examples they are regular numbers that are negatives.
