Which statement is correct about the boundary line and shading for (4x+5y>20)?

Answer and explanation

Correct answer: Dashed line and shading opposite to the origin

Because the sign is (>), the boundary is excluded, and the origin does not satisfy the inequality. So shading is opposite to the origin.
