7a – 5b = 28
(–3, –2)
(–2, –3)
(0, 4)
(4, 0)
3. determine whether the ordered pairs in the form (x, y) are solutions of the given equation and select the correct answer.
yes, both are solutions.
no, neither is a solution.
the first is a solution, but the second is not.
the first is not a solution, but the second is.

(4,0) is the correct answer
because
by putting the co ordinates in equation:
7a-5b=28
7(4)-5(0)=28
28-0=28
28=28
so it is the right answer

You take 1/3, which is the amount you are looking for to fill the rest of the container, then you multiply that times 1/2.  this equals 1/6 of a gallon. then you add that to 1/2 a gallon to find out the total of all the water it takes to fill the bin.  1/2+1/6=3/6+1/6=4/6 or 2/3 gallon simplified.
