Question

n 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. A. (–1, –1) B. (1, –1) C. (3, –1) D. (4, –4)

Answer 1

Here, Reflection is across x - axis
so, the rule says: (x, y) → (x, -y)

Now, Coordinate of S is (1, 1)

Coordinate of it's Image (J) = (1, -1)

In short, Your Answer would be: Option B

Hope this helps!
