Question

When graphing a linear inequality, when can you not use (0,0) as a test point to determine which side of the boundary line to shade?

a. When the point (0,0) is below the boundary line.
b. When the point (0,0) is on the boundary line.
c. When the point (0,0) is part of the solution.
d. When the point (0,0) is above the boundary line.

Answer 1

When graphing a linear inequality, you cannot use (0,0) as a test point when it is below the boundary line.

Step-by-step explanation:

The correct answer is a. When the point (0,0) is below the boundary line. When graphing a linear inequality, we use a test point to determine which side of the boundary line to shade. If the test point satisfies the inequality, then the region containing the test point is shaded. However, if the test point does not satisfy the inequality, then the region on the other side of the boundary line is shaded.
