easiest way to solve is to pick our intercepts first then find the equation. let's use (2,0) as x intercept and (0,½) as y intercept. slope is then (½-0)/(0-2)=-½/2=-¼. now plug in to slope intercept formula to get y=-¼x+½. now we need all integral numbers so multiply through by 4 to get 4y=-x+2 and rearrange into standard form. we get x+4y=2
