The point (1, –5) is reflected across the y-axis. A coordinate plane. What are its new coordinates?
luda_lava [24]
<h3>Answer:  Choice C.   (-1, -5)</h3>

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)
