Answer:
To graph the image of T(10, -2) after a reflection over the x-axis, you simply need to flip the point vertically so that it lies on the opposite side of the x-axis.
The x-coordinate of the point will stay the same, and the y-coordinate will change sign.
Starting with the point T(10, -2), reflect it over the x-axis to obtain the image point T'(10, 2), which is 10 units to the right of the y-axis and 2 units above the x-axis.
So the graph of T(10, -2) after a reflection over the x-axis is the point T'(10, 2), as shown in the following diagram:

------T'(10, 2)

------x-axis------

Note that the x-axis is the line that runs horizontally through the middle of the diagram, while the y-axis is the line that runs vertically through the middle of the diagram. I hope this helps.
