The equation of a line in standard form is ax + by = c, wherein both a and b cannot be zero, and a, b, and c are real numbers. If b != 0, then –a/b is the slope of the line. If a = 0, then it is a horizontal line, and if b = 0, then it is a vertical line. The slope of a vertical line is undefined. Two lines are parallel if they have the same slope or both are vertical lines. Two lines are perpendicular if either one of the lines is horizontal and the other is vertical or the product of their slopes is –1. Design the class lineType to store line. To store a line, you need to store the values of a (coefficient of x), b (coefficient of y), and c (constant). Your class must contain the following operations (functions): a. If a line is nonvertical, then determine its slope. b. Determine if two lines are equal. (Two lines a1x + b1y = c1 and a2x + b2y = c2 are equal if either a1 = a2, b1 = b2, and c1 = c2 or a1 = ka2, b1 = kb2, and c1 = kc2 for some real number k.) c. Determine if two lines are parallel. d. Determine if two lines are perpendicular. e. If two lines are not parallel, then find the point of intersection. f. Add appropriate constructors to initialize variables of lineType. g. Add appropriate accessors and mutators. h. write a program to test your class. Create several lines and test the above functions as showen in the below sample output
