BJP4 Exercise 8.5: slopePoint

Language/Type: Java classes instance methods Point
Author: Will Beebe (on 2016/09/08)

Add the following method to the Point class:

public double slope(Point other)

Returns the slope of the line drawn between this Point and the given other Point. Use the formula (y2 - y1) / (x2 - x1) to determine the slope between two points (x1, y1) and (x2, y2). Note that this formula fails for points with identical x-coordinates, so throw an IllegalArgumentException in this case.

public class Point {
    private int x;
    private int y;
