Knowing how to reflect over the line y = x will come in handy when graphing functions and predicting the graph of inverse functions. Reflect over the y-axis: When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is transformed into its opposite (its sign is changed). Waves refract due to the friction of the continental shelf and the water which slows them down and causes the waves to face more directly to the shore and the wave crests bend.
