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

Solution:

Given, the point (-1, 6)

We have to find the coordinates of the point after a reflection across the x-axis.

A reflection is a common type of transformation.

The x-axis runs left to right whereas the y-axis runs up and down.

When a point is reflected across the x-axis, the x-coordinates remain the same, whereas the y-coordinate changes into its opposite i.e. the sign is changed.

So, the point (-1, 6) changes into (-1, -6)

Therefore, the coordinates of the point after reflection is (-1, -6).

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

Summary:

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