Which of the following inequalites is ( 2,2) a solution?

A: y< -2x + 1

B: y is greater than or equal to 3x - 2

C: y > x - 1

1 answer

To determine if the point (2, 2) is a solution to each of the inequalities, we will substitute \( x = 2 \) and \( y = 2 \) into each inequality and see if it holds true.

A: \( y < -2x + 1 \)
Substituting: \[ 2 < -2(2) + 1 \ 2 < -4 + 1 \ 2 < -3 \] This is false, so (2, 2) is not a solution to inequality A.


B: \( y \geq 3x - 2 \)
Substituting: \[ 2 \geq 3(2) - 2 \ 2 \geq 6 - 2 \ 2 \geq 4 \] This is false, so (2, 2) is not a solution to inequality B.


C: \( y > x - 1 \)
Substituting: \[ 2 > 2 - 1 \ 2 > 1 \] This is true, so (2, 2) is a solution to inequality C.


Conclusion: The only inequality for which (2, 2) is a solution is C: \( y > x - 1 \).
