Point C is the image of C (-4, -2) under a reflection across the y-axis. What are the coordinates of C?

(4,-2)

Step-by-step explanation:

if you reflect a point across the y-axis, that point must be on the same horizontal line then to the pre-mage meaning the y coordinates must remain the same. From their we want the points on both sides of the t-axis to have the same distance. x and -x have the same distance from 0. Therefore this means you will need to take the opposite of X.

So point (x,y) being reflecting over the y-axis will give us (-x,y).

(x , y)--->(-x,y) mean you have (-4,-2)>(4,-2)
