Answer:
Reflection
Step-by-step explanation:
This transformation maps the triangle on the other side of the quadrant.
The size of the triangle did not change
and it was not rotated, because its position did not change
therefore
it underwent
a reflection
The equation for any circle centered at the origin with a radius r is the following:

By looking at the picture, we can see that the radius is 5. We can also use the distance formula to find the distance between (0,0) and (-3,-4), and we will also get 5.
Thus, r=5.
This makes the equation:


That should be your answer, let me know if this is confusing in any way.
Happy Studying~
If AC bisects BD, then BC = CD
That means:
2y - 2 = y + 3
Solve:
y -2 = 3
y = 5
