1. Explain the rule for reflecting a point across the x-axis. What changes and what stays the same?
2. What are the new coordinates of the point (4, -2) after it is reflected across the y-axis?
3. A triangle has vertices at (1, 1), (3, 1), and (3, 4). If the triangle is reflected across the x-axis, what are the coordinates of the new vertices?
