C++ Program

Write a program to calculate the slope between two points x1, y1 and x2, y2. The points should be entered as four double values in the order x1, y1, x2, and y2.

The formula to calculate the slope, m, between two points is,

m = y2 - y1 / X2 - X1

Output the calculated slope value.

Use this value to output the equation of the line in the form

y 5 mx 1 c

You can calculate the value of c from one of the pair of points entered as

input.
