Point C on the triangle has the coordinates (4,6). If it is reflected across the y-axis, what would the new coordinates be for the reflected point C'?
1.(6, −4)
2.−4, 6)
3.(−6, 4)
4.(4, −6)
The reflection across the y-axis changes the x-coordinate to its opposite sign while keeping the y-coordinate the same. Thus, the new coordinates for the reflected point C' would be (-4, 6).
The correct answer is option 2. (-4, 6).
