Reflections: Graph the image

Plot the image of the line segment AB along the y-axis. The coordinates are A(-5,-4) and B(-3,3).

Plotting the points A(-5,-4) and B(-3,3) on paper graph, we get the line segment AB as shown in the adjoining graph.
The reflection of A(-5,-4) on the y-axis is A'(5,-4).
The reflection of B(-3,3) on the y-axis is B'(3,3).
Plotting the reflected points A'(5,-4) and B'(3,3) on the same graph paper and joining The points A' and B', we get the image A'B' of the line segment AB on the y-axis.
