Question

Which inequality will have a solid boundary line and a shaded region above its graph?


x − y ≥ 3




2x − 3y ≤ 3




3y − x < 2




2x + y < 7

Answer 1

Solid line means clearly that it will have equal to sign in inequality. So we can rule out options 3 and 4.

Next use a reference point for the first 2 options and arrive at an answer.

Answer 2

so
2x − 3y ≤ 3 ?
