Point r has coordinates (1, 0). point s is symmetric to point r with respect to the line y = –2.
what are the coordinates of point s?
(points : 10)
(1, –4)
(1, –3)
(–4, 0)
(–5, 0)

The line y = 2, is a horizontal line (parallel to x-axis) that intercepts the y-axis at y = 2. The reflection of a point with coordinates (a,b) through the line y = 2, will be a point with the same x-coordinate and distance to the line y=2 equal to the distance of the point b to the same line. This is the coordinates of the new points will be (a, 2 + 2 - b). So the point (1, 0 ) will transform into (1, 2 + 2 - 0) = (1, 4). (1,4)
