Find the coordinate of L' after a Glide reflection of the triangle: translation 3 units down and 1 unit left then a reflection across the line x = -1.

 b. (2, 0)

Step-by-step explanation:

L = (-3, 3)

down 3 units means subtract 3 from the y-coordinate

new L = (-3, 0)

left 1 units means subtract 1 from the x-coordinate

newer L = (-4, 0)

reflection across x = -1 means measure the distance of the x-coordinate from x = -1 and move it to the other side that same distance. (-4 - (-1) = 3.      -->   -1 + 3 = 2

L' = (2, 0)

b. (2,0)

Step-by-step explanation:

L: (-3,3)

3 units down

(-3,0)

1 unit left

(-4,0)

After reflection:

(2,0)

answer: the value of x is 7cm
