What is the ordered pair solution for -3x+y > 6?
What is the ordered pair solution for 4x - 5y + 20 < 0 ?

-3x + y > 6 is equal to y > 3x + 6 is equal to y > 3(x+2)
so, all pairs of type ( x, y ) where y > 3(x+2) are solutions
4x - 5y + 20 < 0 is equal to 4x < 5y - 20 is equal to x < (5/4)y - 5 is equal to x < 5( (1/4)y - 1 )
so, all pairs of type ( x, y ) where x < 5( (1/4)y - 1) are solutions
hope that helps
