Question:
What is the area bounded by the two lines and the coordinate axes in the first quadrant?
I. The lines intersect at a point which also lies on $3x - 4y = 1$ and $7x - 8y = 5$.
II. The lines are perpendicular, and one of them intersects the Y-axis at an intercept of 4.

The Correct Option is C
Solution and Explanation
I alone: Gives intersection point but not intercepts with axes. Insufficient.
II alone: Gives perpendicular slope relation and one intercept, but missing the other intercept. Insufficient.
Together: We can find both lines’ equations, intercepts, and thus area.
II alone: Gives perpendicular slope relation and one intercept, but missing the other intercept. Insufficient.
Together: We can find both lines’ equations, intercepts, and thus area.
