Larry graphs the inequality x less-than negative 5 using the steps below. Step 1: Draw a number line, and place an open circle at - 5. A number line going from negative 10 to 0. An open circle is at negative 5. Step 2: Shade to the left of - 5 to represent less than - 5. A number line going from negative 10 to 0. An open circle is at negative 5. Everything to the left of the circle is shaded. Step 3: Check work by substitution. x = negative 5 Negative 5 less-than negative 5 False Larry concludes that he must have shaded the number line in the wrong direction. Which best describes the situation? Larry's graph is incorrect. He should have used a closed circle at - 5. Larry's graph is incorrect. He should have shaded to the right of - 5 because the numbers less than - 5 are to the right of - 5. Larry's graph is correct. He should have checked his work using a number to the left of - 5. Larry's graph is correct. He should have checked his work using a number to the right of - 5.
