Write a program that prompts the user to enter the coordinates of two points (1 , 1) and (2 , 2), and displays the slope of the line connects the two points. The formula of the slope is (2 1)/(2 1). Here is a sample run: Sample output: // Red-colored numbers are users input Enter the coordinates for two points: 4.5 -5.5 6.6 -6.5 The slope for the line that connects two points (4.5, -5.5) and (6.6, -6.5) is -0.47619
