3y > 2x + 1
You have asked us to check out the point where x=4 and y=3 .
All we need to do is to plug those numbers in place of 'x' and 'y',
and see whether the resulting statement is true:
3y > 2x + 1
3(3) > 2(4) + 1
On the left side, 3(3) is the same as 9.
On the right side, 2(4) + 1 is the same as (8 + 1) and that's 9 .
So the statement says: 9 > 9 , and that's not true.
9 is equal to 9, it is not greater than 9 .
So this point is not a solution of the inequality.
