The correct Answer is:
To solve the problem, we need to check which of the given options satisfies the three linear equations provided. We will evaluate each equation with the given coordinates. ### Step-by-Step Solution: 1. **Evaluate the first equation**: \[ 4x + 3y = 24 \] We will check the coordinates (9, -4) and (3, 4). - For (9, -4): \[ 4(9) + 3(-4) = 36 - 12 = 24 \quad \text{(True)} \] - For (3, 4): \[ 4(3) + 3(4) = 12 + 12 = 24 \quad \text{(True)} \] Both coordinates satisfy the first equation. 2. **Evaluate the second equation**: \[ 3x - 4y = 1 \] We will check the coordinates (-1, 1), (3, 2), and (-3, 2). - For (-1, 1): \[ 3(-1) - 4(1) = -3 - 4 = -7 \quad \text{(False)} \] - For (3, 2): \[ 3(3) - 4(2) = 9 - 8 = 1 \quad \text{(True)} \] - For (-3, 2): \[ 3(-3) - 4(2) = -9 - 8 = -17 \quad \text{(False)} \] Only (3, 2) satisfies the second equation. 3. **Evaluate the third equation**: \[ 8y - 6x = 4 \] We will check the coordinate (2, 2). - For (2, 2): \[ 8(2) - 6(2) = 16 - 12 = 4 \quad \text{(True)} \] The coordinate (2, 2) satisfies the third equation. ### Summary of Results: - The coordinates (9, -4) and (3, 4) satisfy the first equation. - The coordinate (3, 2) satisfies the second equation. - The coordinate (2, 2) satisfies the third equation. ### Conclusion: The solutions for the linear equations are: - For the first equation: (9, -4) and (3, 4) - For the second equation: (3, 2) - For the third equation: (2, 2)
