Final answer:
The ordered pair describing the location of point M'' after two reflections is (4,-4), corresponding to option b).
Step-by-step explanation:
The question involves reflections in the coordinate plane.
The point M(-4,4) is reflected over the y-axis to create point M'. When a point is reflected over the y-axis, its x-coordinate changes sign, so M' will have coordinates (4,4).
Then, point M' is reflected over the x-axis to create point M''.
A reflection over the x-axis changes the sign of the y-coordinate, so M'' will have coordinates (4,-4).
Therefore, the ordered pair that describes the location of M'' is (4,-4), which corresponds to option b).
