Question

What are the coordinates of the image of point K(1, 3) after a reflection over the line y = –1?

Answer 1

Brandon, draw a picture of the x and y axis, plot the point, plot the line, then you can solve easily.

(1, -5)

3 - -1 = 4 units down from y = -1

x does not change in this reflection
