Step-by-step explanation:

A tree diagram? I don't think so. Probably it would take a year's supply of paper to record all the possibilities. The question really is do you allow duplications and is 0 allowed to be the first digit.

I would think that both are fine.

So the total number for this number would be 10^9. There probably some sort of algorithm to reduce the number and to check if it is a legitimate choice for this number.

Hey there!

To start, you must use the distance formula which is $\sqrt{(x1-x2)^{2}+(y1-y2)^{2} }$ .

x1 and x2 are the x coordinates of the points (it does not matter which one you assign to be x1 and x2) and y1 and y2 are the y coordinates (also does not matter which one you assign to be y1 and y2).

Now, set up your formula and simplify:

$\sqrt{(x1-x2)^{2}+(y1-y2)^{2} }$

$\sqrt{(-12-13)^{2}+(6-8)^{2} }$
