-6x%2B5y=13
5y=6x%2B13
y=%286%2F5%29x%2B13%2F5......plug in all pairs
A (1,19/15)
19%2F15=%286%2F5%291%2B13%2F5
1.27=1.2%2B2.6
1.27=3.8.........not on the line
B (-1/2, 2)
2=%286%2F5%29%28-1%2F2%29%2B13%2F5
2=-0.6%2B2.6
2=2.........is on the line

C (-1/3) (11/5)
11%2F5=%286%2F5%29%28-1%2F3%29%2B13%2F5
2.2=-0.4%2B2.6
2.2=2.2.........is on the line
D (6,-5)
6=%286%2F5%29%28-5%29%2B13%2F5
6=-6%2B2.6
6=-3.4.........not on the line
