Question

Parallelogram ABCD has vertex coordinates A(-4,4), B(-1,4), C(-2, 2), and

D(-5,2). It is reflected across the yaxis. What are the coordinates of C?
O A. (2,-2)
B. (2, 2)
O C. (-2,-2)
O D. (-2,2)

Answer 1

Answer: B

Step-by-step explanation:

If a point with coordinates, (x, y) is reflected over the y axis, the sign of the x coordinate changes while the sign of the y coordinate remains the same. Considering the coordinates of C,

Original coordinates of C = (- 2, 2)

x = - 2 and y = 2

By reflecting over the y axis, it becomes

x = - - 2 and y = 2

x = 2 and y = 2

C' = (2, 2)
