I have to find the distance for the the points -1,1 at 135 degrees. (Find the distance d from the origin to that point) Using the distance formula, I am getting a 0. Is this correct?

It should be obvious that the distance between the point (1,1) and (0,0) is not 0. The formula for distance betwen points A and B is:
Here point A is and point B is .

so 2 squared then?
Not 2 squared, but square root of 2.

What does have to do with any of this?
