4. A triangle with vertices A(1,2), B(3,5), and C(5,-4) is reflected across the y-axis. Provide the transformed coordinates of the
triangle. Show all work.
The transformed coordinates are in the picture. You get these coordinates because when a figure is reflected across the y-axis, the y coordinates stay the same but the x coordinates flip its sign. For example, the 1 turned into -1.
