Question

Plot the image of point A under a reflection across the
y-axis.

Answer 1

(-2,5)

a reflection across the y axis causes for it to basically be reversed along the y axis. meaning if it is at (2,5) then it will be (-2,5)

Answer 2

(-2,5)

Explanation:

A reflection across the y axis (x,y)→(−x,y)

Point A is at (2,5) so it becomes (-2,5)
