Answer

The points that satisfy the inequality are (0, 0) and \(\left(3, \frac{3}{2}\right)\).

Solution

To determine which points satisfy the inequality: \[ -3x + 2y \geq -6 \] Let's evaluate each point by substituting the \( x \) and \( y \) values into the inequality. 1. **Point (4, -5):** \[ -3(4) + 2(-5) = -12 - 10 = -22 \] \[ -22 \geq -6 \quad \text{(False)} \] **Does not satisfy** the inequality. 2. **Point (0, 0):** \[ -3(0) + 2(0) = 0 \] \[ 0 \geq -6 \quad \text{(True)} \] **Satisfies** the inequality. 3. **Point \(\left(3, \frac{3}{2}\right)\):** \[ -3(3) + 2\left(\frac{3}{2}\right) = -9 + 3 = -6 \] \[ -6 \geq -6 \quad \text{(True)} \] **Satisfies** the inequality. 4. **Point (7, -7):** \[ -3(7) + 2(-7) = -21 - 14 = -35 \] \[ -35 \geq -6 \quad \text{(False)} \] **Does not satisfy** the inequality. ### Summary of Points: - ☐ (4, -5) - ☑ (0, 0) - ☑ \(\left(3, \frac{3}{2}\right)\) - ☐ (7, -7) **Points that satisfy the inequality:** \((0, 0)\) and \(\left(3, \frac{3}{2}\right)\).

Beyond the Answer

To determine which points are included in the solution set of the inequality \(-3x + 2y \geq -6\), we can test each point by substituting the \(x\) and \(y\) values into the inequality. 1. For the point (4, -5): \[ -3(4) + 2(-5) = -12 - 10 = -22 \quad (\text{not } \geq -6) \] So, this point is not included. 2. For the point (0, 0): \[ -3(0) + 2(0) = 0 \quad (\text{is } \geq -6) \] So, this point is included. 3. For the point \((3, \frac{3}{2})\): \[ -3(3) + 2\left(\frac{3}{2}\right) = -9 + 3 = -6 \quad (\text{is } \geq -6) \] So, this point is included. 4. For the point (7, -7): \[ -3(7) + 2(-7) = -21 - 14 = -35 \quad (\text{not } \geq -6) \] So, this point is not included. In summary: - (4, -5): Not included - (0, 0): Included - \((3, \frac{3}{2})\): Included - (7, -7): Not included Thus, the points included in the solution set are \((0, 0)\) and \((3, \frac{3}{2})\).
