Define a class Line that has four private instance variables: (x1, y1) and (x2, y2), representing the value of the x-coordinate and y-coordinate of the first point and second point on the line, respectively, in a two-dimensional coordinate system. The following figure shows a line with these two points. (х1, у1) (x2, у2) Figure: A line with two points (x1, y1) and (x2, y2) The class Line has the following instance methods. • findSlope(): the method takes no parameter and returns the slope of the line. The formula for calculating the slope of a line using two points is given below. slope = y2-yı х2-х1 • toString(): the method returns a String containing the values of (x1, yl) and (x2, y2) on a line. As an example, for a line that has two points (3, 4) and (9, 5), the method may return the following String. Line has points (3, 4) and (9, 5) Use appropriate datatype. Your class definition must also include constructors.
