Graph the points (-3, 2) (-6, 3) and (-4,6). Reflect the image over the y axis and graph the new points. You should graph a total of 6 points.

Given pre-image point (-2,5)

Plot the pre-image & image after a reflection over the x-axis

Graph the points (-3, 2) (-6, 3) and (-4,6). Reflect the image over the y axis and graph the new points.

Find K' if the figure is reflected across the x-axis

• (4, 1))
