Question

In the graph above, the coordinates of the vertices of quadrilateral QPRS are Q(2, 4), P(4, 4), R(3, 1), and S(1, 1). If quadrilateral QPRS is reflected across the x-axis to create quadrilateral GHIJ, find the coordinates of point J.

Answer 1

(1, -1)

Explanation:

When you reflect a point (x, y) across the x-axis, its coordinates

become (x, -y).

Thus, when you reflect point S to Point J, the coordinates change from (1, 1) to (1, -1).
