Chapter 3, Problem 32PE

(Algebra: slope-intercept form) Write a program that prompts the user to enter the coordinates of two points $\text{(x1,}\text{y1)}\text{and}\left(\text{x}2\text{,}\text{y2}\right),$ and (x2, y2), and displays the line equation in the slope-intercept form, i.e., $y=mx+b.$ For a review of line equations, see www.purplemath .com/modules/strtlneq.htm. m and h can he computed using the following formula:

$m=\left(y_2-y_1\right)\left(x_2-x_1\right)b=y_1-m{x}_1$

Don't display m if it is 1 and don't display b if it is 0.
