Question

P (-2, 3) is reflected in the x- axis. What is the coordinate of its image? Graph and state the coordinates of P

Answer 1

A reflection in x-axis is a transformation expresive by the equation:

`(x,y)\to(x,-y)`

In this case, the point P = (-2, 3) transform to P' = (-2, -3), the coordinate of its image is -3.
