Easiest way, since you don't specify which form you want your equation in.
(based on the fact that for Ax + By = C 0, the slope is A/B)
1. Slope = 1/2
so the equation is x + 2y = C
plug in point, 5  2 = C
C = 3
so ..... x + 2y = 3
from there you can change it to any form they ask for.
try the second one the same way.
