Consider the distance formula for three dimensions once again. _ 1i 2 2 2 d_ (x2' x1) + (yz-y1) + (Z;- 21) Note: Once you complete this activity, you will move on to Discussion 1 on the Discussion Board. On the Discussion Board, you will: List and explain valid reasons for the following situations. - Explain what would change if you're trying to find the distance for a point P (x, y, z) to a point on they axis? - Explain what would change if you're trying to find the distance for a point P (x, y, z) to a point on the z axis
