1. Write a program that will allow a user to calculate the slope of a line. The user will provide the data for the coordinates of the end of the points of the line (xl, yl) and (x2, y2). The program should allow the user to make 20 calculations. Recall that the slope of a line is given 25.2 Slop Use the following end-point coordinates and sample output to help you test your program Linel 1.5) (x2.y2) - (4, 3.2) Line 2: (xl.yl) (2 1) (x2.y2)-(2 3) Line 3 5) 5) (xl.yl) (3, (x2.y2)-(-5, Line 4 (xl.yl)- (x2.y2)- 1.
