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.

Answer: 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)
Answer:
b. (2,0)
Step-by-step explanation:
L: (-3,3)
3 units down
(-3,0)
1 unit left
(-4,0)
After reflection:
(2,0)
