Alfonso graphs the inequality x greater-than negative 8 using the steps below. Step 1: Draw a number line, and place an open circle at –8. A number line going from negative 13 to negative 3. An open circle is at negative 8. Step 2: Shade to the left of –8 to represent the infinite solutions to x greater-than negative 8. A number line going from negative 13 to negative 3. An open circle is at negative 8. Everything to the left of the circle is shaded. Step 3: Check work by substitution. x = negative 9 Negative 9 greater-than negative 8 False Which best describes the situation? The graph is incorrect. He should have used a closed circle at –8. The graph is incorrect. He should have shaded to the right of –8. The graph is correct. He should have checked his work with a number that was not on the shaded portion of the graph.

Your answer is B. The graph is incorrect. He should have shaded to the right of –8.

He did not shade to the right but he shaded to the left.

Hope this helps :D
