Question

The vertices of a triangle are P(-2,-4), Q(2,5), and R(-1,-8). Name the vertices of the image reflected in the y-axis.

Answer 1

To reflect a triangle in the y-axis, change the signs of the x-coordinates of the original triangle.

Step-by-step explanation:

To find the vertices of the image reflected in the y-axis, we need to change the signs of the x-coordinates of the original triangle. The vertices of the original triangle are P(-2,-4), Q(2,5), and R(-1,-8). When we reflect these points in the y-axis, the x-coordinates change their signs. Therefore, the vertices of the reflected triangle are P'(2,-4), Q'(-2,5), and R'(1,-8).
