Answer:

(4, -2)

Explanation:

You want the coordinates of the point (-4, -2) after its reflection across the y-axis.

Reflection

The x-coordinate of a point tells you its horizontal distance from the y-axis. When a point is reflected across the y-axis, it is moved to the other side by the same distance. That is, the sign of the x-coordinate changes.

(x, y) ⇒ (-x, y) . . . . . . . reflected across the y-axis

(-4, -2) ⇒ (4, -2) . . . . . reflected given point

The coordinates of the reflection are (4, -2).
