Find all points(s) of intersection of the line y=2x and the circle x^2+y^2=5
A) (1,2)
B) (1,2) and (-1, -2)
C) (1/2, 1) and (-1/2, -1)
D) (sqrt15/3, 2 sqrt15/3) and (sqrt15/3, -2 sqrt15/3)

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.
