Always remember the below rule, though it marginally helps you in this question but it will definitely help you on your GMAT.
for ax+by+c = 0
x intercept = -c/a
y intercept = -c/b
slope = -a/b
x intercept is 4, slope is positive
slope =-a/b
since x intercept is positive the y intercept has to be negative. Eliminate all the positive options
if y intercept is negative and slope is positive
the line is passing through negative y axis or the fourth quadrant.
area = 1/2 * x intercept * y intercept
12 = 1/2 * 4 * y
y intercept = -6, since it has to be negative for slope to be positive.
Hope this helps.
