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'?

Answer 1

When a point is reflected across the y-axis, its x-coordinate changes sign while the y-coordinate remains the same.

Therefore, if point C has coordinates (4, 6), its reflection across the y-axis would have coordinates (-4, 6).

So, the new coordinates for the reflected point C' would be (-4, 6).
