Question

Given points J(1,4), A(3,5), and G(2, 1), whatare the coordinates of AJ'A'G' whenreflected over the x-axis?

Answer 1

When dealing with reflections over the x-axis, the only thing that we need to do is to negate the y-coordinate of the original figure.

The rule is: f(x, y) → f(x, -y).

Original Figure → Translated Figure

J (1, 4) → J' (1, -4)

A (3, 5) → A' (3, -5)

G (2, 1) → G' (2, -1)

Here is how it looks like when plotted. (Green is the original figure and Blue is the reflected figure)
