Question

A triangle in the coordinate plane has coordinates of (2,3), (-4,-5), and (-2, 4). It is reflected about the x-axis. What are its new coordinates?

Answer 1

Since the only transformation is a reflection about the x-axis, the only thing that changes is that the y-coordinates are multiplied by negative one. In this case, the points become:

(2,-3), (-4,5), (-2,-4)
