Warm Up
• Translate the following coordinates:
(-3, -2)(-2, 2)(0,4) (x + 2, y – 4)
On the graph to the right, translate the
Figure (x + 4, y – 3)

• To mathematically describe a reflection using coordinate notation, you write it as the following:
(x,y) (x, -y) (x,y) (-x, y)

Is this a reflection?
• A figure has line symmetry if a line, called the line of symmetry, divides the figure into two parts that are reflections of each other in the line
