Problem with making balls bounce off world edge

Here is my problem: 1. Each ball must move at a random speed in each of the X- and Y-directions, which speed may vary between 0 and 5 pixels per direction when the instance is created but stays constant for the lifetime of the ball. 2.The balls must bounce off the edges of the world in such a way that the angle of incidence equals the angle of reflection. I am struggling the most with the second problem. Any help will be appreciated. Thanks.

Is the problem that you don't understand what it means, or you don't know how to achieve it?

Remember that you are considering the horizontal and vertical (axial) movement separately. Hint: movement is a product of speed and __________? (you will need fields for both when considering each axis) Hint2: which of these two factors change when a bounce occurs? and how?
