In round 2, he lost 7 points. which expression shows how many total points he has at the end of round 2? 2 + (−7) = −5, because −5 is 7 units to the left of 2 2 + 7 = −5, because −5 is 7 units to the left of 2 2 + (−5) = −7, because −7 is 5 units to the left of 2 2 + 5 = −7, because −7 is 5 units to the left of 2.

2 + (−7) = −5, because −5 is 7 units to the left of 2

Step-by-step explanation:

Point S is on 2 on the number line shows Samuel's score after the first round of a quiz.  In round 2, he lost 7 points

At first point S is 2 on the number line

So S is 2

in the second round he lost 7 points

for lost , subtract 7 from 2

so the point S is on -5 on round 2

2 + (−7) = −5, because −5 is 7 units to the left of 2
