Question

The reflection of a Quadrant II point is located in Quadrant I. Assuming no error was made, what kind of reflection occurred?

A reflection across the x-axis
A reflection across the y-axis
A reflection across both axes

Answer 1

A reflection across the y-axis.

Explanation:

If it was across the x-axis, the point would have gone into Quadrant III.

The y-axis is vertical, and it was moved into Quadrant I from Quadrant II making it a vertical reflection which is a reflection from the y-axis.

Answer 2

A reflection across the y- axis

Explanation:

Under a reflection in the y- axis

a point (x, y) → (-x, y)

A point in the second quadrant (- x, y)

Under reflection in the y- axis is (x, y) ← point in first quadrant
