Question

A triangle has vertices P(-5, 1), Q(-2, 3) and R(2, 0). If the triangle is reflected over the y-axis, what are the coordinates of P'?

A) P'(-5, -1)
B) P'(5, 1)
C) P'(5, -1)
D) P'(-5, 1)

Answer 1

The coordinates of P' after reflecting the triangle over the y-axis are (5, 1).

Step-by-step explanation:

The question asks for the coordinates of point P' when the triangle with vertices P(-5, 1), Q(-2, 3), and R(2, 0) is reflected over the y-axis. To find the reflection of a point over the y-axis, you change the sign of the x-coordinate while keeping the y-coordinate the same.The original coordinates of point P are (-5, 1). When we reflect P over the y-axis, the x-coordinate changes sign, becoming 5, while the y-coordinate remains unchanged. Therefore, the coordinates of the reflected point P' are (5, 1).
