Find the glide reflection image of the black triangle where the translation is (x, y) > (x, y - 7) and line of reflection is x - 1

Transformation involves changing the position of a shape.

The image of the black triangle is option (d)

The coordinates of the black triangle are:

When the triangle is transformed by

The new coordinates are:

When the triangle is reflected across the line

The rule of transformation is:

So, we have:

So, the coordinates of the image of the triangle are:

The above coordinates are illustrated by the option (d)
