Example 1: Reflect triangle GLQ across the x-axis. Then state the coordinates of the image. Then on the same coordinate plane reflect the ORIGINAL image across the y- axis. Reflected Across x-axis G = (3,4) G ’ =________ L = (1,2) L ’ = ________ Q = (4,-1) Q ’ =________ Reflected Across y-axis G = (3,4) G ’ =________ L = (1,2) L ’ = ________ Q = (4,-1) Q ’ =________

Example 2: Reflect the image across the line y = 1.
Example 3: Reflect the image with points F (2,2) W (2, 5) and K( 3, 3) across the line x= 3.
What s the rule for reflection across the line y =x. b) Reflect point B( 2, 3) across the line y =- x. What s the rule for reflection across the line y = - x .
Example 6: Reflect the figure below across the line y = x.
