If a point A is reflected across the x-axis, the x-coordinate remains the same and the y-coordinate is negated.
Given that the coordinate A is (-3 1/2, 4), the y-coordinate is 4. When the point A is reflected across the x-axis, its y-coordinate becomes -4.
Therefore, the coordinates of A' are (-3 1/2, -4).
If the coordinate A (-3 1/2, 4) is reflected across the x-axis, what will the coordinates of A' be?
