Answer 2

We can use the distance formula to find this, and since only one of the answers lets find the distance between point D and the Origin.
O\(\large(0,0)\)
D\(\large(-9,9)\)
The distance formula: \(\sqrt{(x2-x1)^2+(y2-y1)^2}\)

Answer 3

I think its B or C

Answer 4

\(\sqrt{(-9-0)^2+(9-0)^2}\)
\(\sqrt{(-9)^2+(9)^2}\)=\(\sqrt{81+81}\)=\(\sqrt{162}\)
This is wrong... lets solve for the distance to J
O\((0,0)\)
J\((-9,0)\)
\(\sqrt{(-9-0)^2+(0-0)^2}\)=\(\sqrt{81}\)
This is correct. lets solve for P
O\((0,0)\)
P\((0,-9)\)
\(\sqrt{(0-0)^2+(-9-0)^2}\)=\(\sqrt{81}\)
There is your answer! It is J,P
