Answer:
Option b is right answer.
Horizontal translation of 6 units
Step-by-step explanation:
Given that L and L' are congruent triangles.
. Figure L has vertices at negative 4, 2, negative 2, 4, and negative 3, 7. Figure L prime has vertices at 2, 2, 4, 4, and 3, 7
On comparison of corresponding vertices we find that y coordinate remains the same for all vertices.
But x coordinate -4 became 2, -2 became 4, and -3 became 3.
This means original x coordinate is increased by 6 units to get L'
i.e. there is a horizontal translation of 6 units.
This will only make (-4,2) to (2,2), (-2,4) to (4,4) and (-3,7) to (3,7)
Option b is right answer.
Horizontal translation of 6 units
