Question

The vertices of AABC are A(-2,5), B(-2,3), and C(-5,3). If AABC is reflected across the line y = -1 to produce the image AA'B'C', find the coordinates of the vertex C'.

Answer 1

The x-coordinate of C' will still be -5, but the y-coordinate of C' will be -3.

Step-by-step explanation:

To find the coordinates of the vertex C', we need to reflect the coordinates of point C(-5,3) across the line y = -1. When reflecting a point across a line, the x-coordinate remains the same while the y-coordinate changes sign. So, the x-coordinate of C' will still be -5, but the y-coordinate of C' will be -3.
