CJ and Marlene asked to plot the points (-61/2,3) on a coordinate grid in the work is shown Who is correct? What mistake did the other make

1 answer

To determine who is correct in plotting the point \((-61/2, 3)\) on a coordinate grid, let's first clarify how to plot the point correctly.

  1. Understanding the Coordinates: The point \((-61/2, 3)\) has:

    • The x-coordinate: \(-61/2\), which is equivalent to -30.5.
    • The y-coordinate: \(3\).
  2. Plotting the Point:

    • Start at the origin (0, 0).
    • Move left along the x-axis to -30.5 (which is halfway between -30 and -31 on the grid).
    • From -30.5, move up to \(3\) on the y-axis.

If CJ plotted the point correctly at \((-30.5, 3)\) and Marlene made a mistake with either the x-coordinate or y-coordinate, we would determine that CJ is correct, and Marlene likely either miscalculated -61/2 or plotted the y-coordinate incorrectly.

To conclude, without the actual work shown by CJ and Marlene, we can't definitively say who is right or what the specific mistake was; however, verifying the conversion of the fraction and ensuring proper direction on the grid would clarify any discrepancies.

If you provide CJ and Marlene's specific plots, I can help identify the exact mistakes and conclude who was correct.
