Visual C++ - Calculating Slope of a Line Given Two End Points
Here is the Visual C++ program for Calculating Slope of a Line Given Two End Points
It uses the following formula given points are (x1,y1) and (x2, y2)
slope = (y2 - y1) / (x2 - x1)
Source Code
#include <iostream>
#include <math.h>
void main()
{
float slope;
float x1, y1, x2, y2;
float dx, dy;
std::cout << "Program to find the slope of a line given two end points\n";
std::cout << "Enter X1: ";
std::cin >> x1;
std::cout << "Enter Y1: ";
std::cin >> y1;
std::cout << "Enter X2: ";
std::cin >> x2;
std::cout << "Enter Y2: ";
std::cin >> y2;
dx = x2 - x1;
dy = y2 - y1;
slope = dy / dx;
std::cout << "Slope of the line with end points (" << x1 << ", " << y1 << " and (" << x2 << ", " << y2 << ") = ";
std::cout << slope << "\n";
}
Output
Program to find the slope of a line given two end points
Enter X1: 2.5
Enter Y1: 7.5
Enter X2: 12.5
Enter Y2: 18
Slope of the line with end points (2.5, 7.5 and (12.5, 18) = 1.05
