a y < -2x + 1
b y > 3x - 2
c y > x - 1

1 answer

To determine which inequalities the point (2, 2) satisfies, we will substitute \(x = 2\) and \(y = 2\) into each inequality and check if the inequality holds.

a) \(y < -2x + 1\)

Substituting \(x = 2\) and \(y = 2\):

\[ 2 < -2(2) + 1 \]

Calculating the right side:

\[ -2(2) + 1 = -4 + 1 = -3 \]

So the inequality is:

\[ 2 < -3 \quad \text{(False)} \]

b) \(y > 3x - 2\)

Substituting \(x = 2\) and \(y = 2\):

\[ 2 > 3(2) - 2 \]

Calculating the right side:

\[ 3(2) - 2 = 6 - 2 = 4 \]

So the inequality is:

\[ 2 > 4 \quad \text{(False)} \]

c) \(y > x - 1\)

Substituting \(x = 2\) and \(y = 2\):

\[ 2 > 2 - 1 \]

Calculating the right side:

\[ 2 - 1 = 1 \]

So the inequality is:

\[ 2 > 1 \quad \text{(True)} \]

Conclusion

The only inequality that (2, 2) satisfies is:

c) \(y > x - 1\)

So the answer is c only.
