Answer:
(C) (2, -2)
Step-by-step explanation:
Given the linear equation: 
A second linear equation is given by the table:

Clearly, this is a graph of y=-x as each y-value is a negative of its x-value.
Therefore if:

Recall: y=-x
Therefore: y= -2
Therefore, a solution to the system of equations is (2, -2)
B) 2.5 hours , because 8 mph is 1 hour and the another 8mph is 1 hour 8+8mph =16mph 1+1hr=2hr half of 8 is 4mph is .5hr so therefore 8+8+4=20mph 1+1+ 30mins= 2.5hr
