wait, how would I know which one is X1 and which one is Y2
For both of them? :?

ivettef365 · Answer

just enter the points, first point (x1,y1) = (4, -3)
second point (x2,y2) = (-4,3)

ivettef365 · Answer

it really doesn't matter which point you enter first, the distance would still be the same

falco276 · Answer

oh, ok.

If you are using an online calculator to compute something that your teacher expects you to know how to do with the formula, you aren't really grasping the concept of the lesson. Eventually, if you ever have to answer this question on a test where you can't use the calculator, you will have no idea what to do.

The tool might be great for checking your work, but I would strongly urge you to make sure you understand how to do the problem without it.
