Answer:
-2 Â Means Day 2 Â & 21 is commute time
Step-by-step explanation:
The coordinate plane below shows some of his commute times in the last two weeks.
See attached graph
Yesterday  means - 1
Days  8 means  - 8 Â
Day 9 means   -8
- 8 has dot  on  24  => Commute time on Days 8  = 24 minutes
-9 has dot  on  18  => Commute time on Days 9 = 18 minutes
2 days ago, Â Paulo's commute time was halfway between his commute times 8 and 9 days ago.
=> Commute time on Days 2 Â =(24 + 18)/2 = 21
Day 2 Â = Â - 2
Coordinate  = (-2 , 21 )    Â
-2 Â Means Day 2 Â & 21 is commute time
