If ABC is reflecting across the y-axis ,what are the coordinates of c’?

Explanation:
First step is to locate point C. It is at location (6, 3)
Reflecting this over the y axis will change the sign of the x coordinate, while keeping the y coordinate the same. We go from (6, 3) to (-6, 3)
The algebraic rule for this is [tex](x, y) \to (-x,y)[/tex]
Therefore, point C' is located at (-6, 3)
