The answer is c. To get to (-2,1) from (5,-4), you have to add subtract 7 from 5 and add 5 to 1.
An hour is 60 minutes.
The trip to the arena + The return drive = 60 mintues.
Since the return drive is 8 minutes shorter, if you added 8 minutes it would be the same length as the trip to the arena.
The return drive + 8 minutes = The trip to the arena
Let's represent these two equations with variables.
x + r = 60
r + 8 = x
What we do now is use substitution. Since r + 8 = x, we can replace x from the first equation with r + 8.
x + r = 60
r + 8 + r = 60
2r + 8 = 60
2r = 52
r = 26
Then use r in an earlier equation to find a.
r + 8 = x
26 + 8 = x
x = 34
