What are the coordinates of the point (1, 6) after reflecting it across the x-axis?

When reflecting a point across the x-axis, we only change the sign of the y-coordinate. The x-coordinate remains the same.

For the point (1, 6):

• The x-coordinate is 1.
• The y-coordinate is 6. After reflection, it becomes -6.

Thus, the new coordinates after reflection across the x-axis will be:

(1, -6)

So, the coordinates of the point (1, 6) after a reflection across the x-axis are (1, -6).
