Question

pentagon pqrst and its reflection, pentagon pqrst, are shown in the coordinate plane below: what is the line of reflection between pentagons pqrst and pqrst? x = 1 y = x x = 0 y = 0

Explanation:

Step1: Observe the x - coordinates

The x - coordinates of corresponding points of pentagons PQRST and P'Q'R'S'T' have opposite signs while the y - coordinates remain the same. For example, if a point in PQRST has coordinates (x,y), the corresponding point in P'Q'R'S'T' has coordinates (-x,y).

Step2: Recall reflection rules

A reflection across the y - axis (the line x = 0) changes the sign of the x - coordinate of each point while keeping the y - coordinate the same.

Answer:

C. x = 0
