2,5

anonymous · Answer

Try the first coordinate for x and the second for y. Example: (2,5)
5 > -3*2 + 3 -> 5 > -3 which is correct
5 > 2 + 2 -> 5 > 4 which is also correct. Try out the other points to see if there's anything left.

we could do it right way. Make the graphice for the two lines. We see that the area where y> x isupper, so both answers are positive
