If the point (-2, 5) is reflected across the y-axis, its image will be at (-2, -5).

True the image will be at ( -2, -5 )

Explanation:

according the question the X and Y coordinates of the reflected image was given as ( -2, 5 ).and for the image to have a reflection across the Y axis it means the value of the reflected image on the Y axis will change from either positive to negative or from negative to positive.

hence the image will be at ( -2, -5 )  therefore the answer is True the image will be at ( -2, -5 )  

for the reflection an object/image to occur on a particular side of an image dimension the original value of the image at that dimension has to take the opposite value
