Step 1: Draw a number line, and place an open circle at 8, 13-1211-109-8-7 -8-5 4-3
Step 2: Shade to the left of9 to represent the infinite solutions to x-8.
13-12-11-10-9 -8-7 -8-5-4 3
Step 3: Check work by substitution.
X-9
-9>-8 False
Which best describes the situation?
O The graph is incorrect. He should have used a closed circle at-8.
O The graph is incorrect. He should have shaded to the right of -8.
O The graph is correct. He should have checked his work with a number that was not on the shaded portion of the
graph.
