Answer 1

Answer:

(4,-2)

Step-by-step explanation:

If we are reflecting a point across the y-axis, that point must be on the same horizontal line that the pre-mage is was, this means the y coordinate must remain the same.  Now we want the points on both sides of the y-axis to have the same distance.  x and -x have the same distance from 0. This means you will need to take the opposite of x.

So a point (x,y) being reflected over the y-axis will give (-x,y).

( x  , y)->(-x,y) means we have:

(-4,-2 )->(4,-2)

You can graph this to confirm it looks like a reflection through the y-axis.
