Question

A point P has coordinates (-5, 4). What are its new coordinates after reflecting

point Pover the y-axis?
A. (-5, -4)
B. (-5, 4)
C. (5, 4)
D. (5, -4)

Answer 1

(5, 4)

Explanation:

when you reflect off the y-axis, you switch (x,y) to (-x,y)

So

(-5, 4) --> (5, 4)

Hope this helps,

Feel free to ask more questions if I need to explain more.

Answer 2

C(5, 4)

Explanation:

The rule for a reflection over the y -axis is (x,y)→(−x,y) .
