To determine who is correct between CJ and Marlene when plotting the point \((-61/2, 3)\), we first need to understand the coordinates involved:
1. The x-coordinate is \(-61/2\), which simplifies to \(-30.5\). This means the point is located 30.5 units to the left of the origin on the x-axis.
2. The y-coordinate is \(3\), meaning the point is located 3 units above the origin on the y-axis.
When plotting this point:
- You start from the origin (0, 0).
- Move to the left along the x-axis to \(-30.5\).
- Then move up to the coordinate \(3\).
### Corrections:
- Check where CJ plotted the point. He should have plotted at \((-30.5, 3)\). If he plotted at, for example, \((30.5, 3)\), he would be incorrect as this would place the point on the right side of the y-axis instead of the left.
- Now check Marlene's plotting. If she also made a mistake by possibly plotting the point somewhere else (like \((-30.5, -3)\)), she would also be incorrect as that would put the point below the x-axis instead of above.
### Conclusion:
- Correctness depends on whether CJ and Marlene accurately placed the point at \((-30.5, 3)\).
- If one of them plotted the point in the correct position, they are correct, and the other made a mistake either in the sign of the x-coordinates or y-coordinates, or possibly in the values themselves.
For a definitive answer, we would need to see the specific plots created by CJ and Marlene.
