Point N on the number line shows Rob's score after the first round of a quiz: A number line is shown from negative 8 to 0 to positive 8. There are increments of 1 on either side of the number line. The even numbers are labeled on either side of the number line. Point N is shown on 1. In round two, he lost 6 points. Which expression shows how many total points he has at the end of round two? 1 + (−6) = −5, because −5 is 6 units to the left of 1 1 + 6 = −5, because −5 is 6 units to the left of 1 1 + (−5) = −6, because −6 is 5 units to the left of 1 1 + 5 = −6, because −6 is 5 units to the left of 1
