Point P on the number line shows Lara'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 P is shown on 3. In round two, she lost 4 points. Which expression shows how many total points she has at the end of round two? (5 points) Group of answer choices 3 + 1 = −4, because −4 is 1 unit to the left of 3 3 + (−1) = −4, because −4 is 1 unit to the left of 3 3 + 4 = −1, because −1 is 4 units to the left of 3 3 + (−4) = −1, because −1 is 4 units to the left of 3
