ANSWER

P'(2,7)

EXPLANATION

When we reflect a point in the y-axis, we negate the x-coordinates.

The rule for reflection across the y-axis is

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

The given point, P has coordinates (-2,7)

To obtain the coordinates of the image P', we negate the x-coordinate of P(-2,7).

P( - 2,7) \to \: P'( -  - 2,7)

P( - 2,7) \to \: P'(2,7).
