Triangle ABC has coordinates A(1, 4); B(3, –2); and C(4, 2). Find the coordinates of the image A'B'C' after a reflection over the x-axis.

1 answer

in a reflection over the x-axis, all your x values stay the same, the y's go opposite

A(1,4) -----> A' (1,-4)

Do the others the same way.

Check by plotting the old and the new.
