<h2>Reflection.</h2>Step-by-step explanation:
The image attached shows a representation of the problem, there you can observe the congruence between triangles.
Also, using the images you can easily deduct the transformation we need to map one triangle onto the other one, we just need to reflect one triangle across and axis that pass through point M, such line acts like a mirror.
Therefore, the right answer is reflection.
<h3>Solution and Explanation:</h3>
If and
are directly proportional, then they must have a common scalar.
To find we must first find its scalar. If we let
be the scalar we can form the equation,
.
We are given the information that if then
. We can use that in finding the scalar.
Now we can solve for when
knowing that our scalar is
.
when
