The image of l (2,0) under a reflection in point p is l' (0,4). find k', the image of k (4,-5) under a reflection in p.

If I'm reading this question correctly you just have to find the difference of the first point given (L to L'). Once you find the difference of this point because it's a reflection all the other point will follow the same rule. So by applying this same rule you can figure out where K' is because you already have the original K
