Question

how do i find out if the ordered pair is a solution of an ordered pair?
2x+2y is less than or equal to 0; (-1,-1), (1,1)

Answer 1

solution of an inequality..

Answer 2

Put -1=x and -1=y to check if (-1,-1) is a solution.
Similarly, put x=1 and y=1 to check if (1,1) is a solution.
2(-1)+2(-1)=-2-2=-4 which is less than 0 so (-1,-1) is a solution.
Also, 2(1)+2(1)=2+2=4 which is NOT less than 0 so (1,1) is NOT a solution.

Answer 3

okay, thank you, that seems simple enough!
