Question

Triangle ABC has vertices A(-5,8), B(10,1), and

C(-4,-9). What are the vertices of the image after it is
reflected over the y-axis?

Answer 1

The vertices of the image after it is reflected over the y-axis are:

A'(5, 8), B'(-10, 1), and C'(4, -9)

What are the coordinates after transformation?

The coordinates of triangle ABC are given as:

A(-5,8), B(10,1), and C(-4,-9)

Now, the transformation that shows a reflection over the y-axis is:

(x, y) → (-x, y)

Thus, the coordinates after the transformation are:

A'(5, 8), B'(-10, 1), and C'(4, -9)
