Answer: OPTION C.

Explanation:

Observe the figure.

You can identify that the vertices of the triangle T are:


(2,1),(1,2),(4,1)

And the vertices of the triangle T' are:


(-3,1),(-4,2),(-1,1)

You can notice that the y-coordinates of the triangle T and the y-coordinates of the triangle T' are equal, but the x-coordinates change; these are translated "k" units to the left.

You can pick the x-coordinates of the vertices
(2,1) and
(-3,1) and write the following equation:


2+k=-3

Solving for "k", you get:


k=-3-2\\\\k=-5

Therefore, the translation from T to T' is 5 units left.
