The numbers in parentheses are partial ordered pairs. You are given one of the pair of coordinates. The first coordinate is always the value of 
and the second coordinate is always the value of 
(hence the name ordered pair).
So if you are given the first number in the ordered pair, replace in the given equation with that value and then do the arithmetic to find out the value of that results.
For example, your problem #5. Replace the with -6
\ -\ 7)
Now do the arithmetic to determine the value of
Do the others the same way. In number 7 and 8, you are given the value of , so substitute for and then calculate .
