Pentagon PQRST is shown on the grid. A student reflected pentagon PQRST across the y-axis to create hexagon P՚Q՚R՚S՚T՚.

Which rule describes this transformation?

b (x, y) → (x, -y)
c (x, y) → (-x, y)
d (x, y) → (-y, x)

The correct answer is c (x, y) → (-x, y). This transformation reflects the pentagon across the y-axis, so the x-coordinate of each point is negated while the y-coordinate remains the same.
