1 2 3 4 5 -5 -4 -3 -2 -1 x y 3

Action: reflect point over the x axis 1 2 3 4 5 -5 -4 -3 -2 -1 x y Action: reflect point over the x axis Result: x is same y is opposite

1 2 3 4 5 -5 -4 -3 -2 -1 x y Result: y is the same X is opposite

1 2 3 4 5 -5 -4 -3 -2 -1 x y Result: x is opposite Y is opposite

1 2 3 4 5 -5 -4 -3 -2 -1 x y Reflect over x axis

1 2 3 4 5 -5 -4 -3 -2 -1 x y Reflect over x and y axis

1 2 3 4 5 -5 -4 -3 -2 -1 x y Reflect over x and y axis

1 2 3 4 5 -5 -4 -3 -2 -1 x y Reflect over y axis

1 2 3 4 5 -5 -4 -3 -2 -1 x y Reflect over x and y axis

1 2 3 4 5 -5 -4 -3 -2 -1 x y Reflect over x axis

1 2 3 4 5 -5 -4 -3 -2 -1 x y Reflect over y axis

1 2 3 4 5 -5 -4 -3 -2 -1 x y Reflect over x and y axis

To reflect points over the x axis use the opposite of the y coordinate To reflect points over the y axis use the opposite of the x coordinate To reflect a point to the opposite quadrant use the opposite of both coordinates

1 Reflection over the y axis 2 Reflection over the x axis 3 (5,-2) 16

1 Reflection over the y axis 2 Reflection over the x axis 3 (8,2) 17

1 Reflection to opposite quadrant 2 Reflection over the y axis 3 (-4,-6) 18

1 Reflection over the x axis 2 Reflection over the y axis 3 (-5,2) 19
