(1,3) and (-2,-6) are the only ones that apply. 
All you do is substitute all four of the coordinates back into the equation:
A. 3=3(-1)    3=-3    So the first choice does not work.
B. 5=3(2)     5=6     So the second choice doesn't work
C. 3=3(1)     3=3     So the third choice works
D. -6=3(-2)  -6=-6   So the fourth choice works
