Question

The point (1, –5) is reflected across the y-axis. A coordinate plane. What are its new coordinates?

(–1, 5)
(1, –5)
(–1, –5)
(1, 5)

Answer 1

the answer is c ...........

Answer 2

Answer: Choice C. (-1, -5)

Step-by-step explanation:

The reflection rule we use is

`(x,y) \to (-x, y)`

when we want to reflect over the y axis. The x coordinate flips from positive to negative, or vice versa, while the y coordinate stays the same.

Therefore,
`(1, -5) \to (-1, -5)`
