Which statement is true about the graph of y ≥ -2x + 6?
Which statement is true about the graph of ?
Answer and explanation
Answer: D: The boundary line is solid, and the point (0,0) is not a solution.
The inequality includes equality, so the boundary line is solid. A dashed line is used only for strict inequalities. Test the origin: is ? No, since . So is not a solution, and the shaded region is above the line, away from the origin. That makes D correct. Choices A and C claim a dashed line, which is wrong because of the "or equal to". Choice B has the right line style but wrongly states that is a solution.
