Answer:

(5, 1)

Explanation:

Reflection across the x-axis negates the y-coordinate:

(x, y) ⇒ (x, -y) . . . . reflection across the x-axis

Rotation 90° CCW is the transformation ...

(x, y) ⇒ (-y, x) . . . . rotation 90° CCW

The two transformations together give ...

(x, y) ⇒ (y, x) . . . . reflection across the x-axis, then rotation 90° CCW

For point B, this gives ...

B(1, 5) ⇒ B'(5, 1)
