Answer:When a shape is reflected across the y-axis on a coordinate grid, the x-coordinate of each point is negated while the y-coordinate remains the same.
If the center of the original circle was located at (x, y), after the reflection across the y-axis, the x-coordinate becomes its opposite (-x), while the y-coordinate remains unchanged. Therefore, the new coordinates of the center of the circle would be (-x, y).
