I have to reflect y=-3 across the points (-6,-5), (0,-5), (1,-3), (-6,-3)

Answer 1

The best way is to plot those original points on x-y graph. If you connect the points you'll see that it forms a retangle.

Draw a y = -3 line and reflect the points across y = -3 line.

(1,-3) and (-6,-3) are on y = -3 therefore no change.

Final answer:

(-6,-1), (0,-1), (1,-3), (-6,-3)
