Write a single translation that is equivalent to T followed by T

Explanation:

means we move x units to the right and y units up. If x is negative, then you move left. If y is negative, then you move down.

means you move 3 units to the right (x is positive) and 1 unit down (y is negative).

means you move 5 units to the left (x is negative) and 5 units up (y is positive)

------------

Since we move 3 units to the right and then 5 units to the left, overall we moved 3+(-5) = -2 units to the right or 2 units to the left

Since we move 1 unit down and 5 units up, we moved -1+5 = 4 units up overall.

Overall, we move 2 units to the left and 4 units up which is represented by
