Programa para hallar la pendiente de una recta

Dadas dos coordenadas, encuentre la pendiente de una línea recta.

Ejemplos: 

Input  : x1 = 4, y1 = 2, 
         x2 = 2, y2 = 5 
Output : Slope is -1.5

Enfoque: para calcular la pendiente de una línea, solo necesita dos puntos de esa línea, (x1, y1) y (x2, y2). La ecuación utilizada para calcular la pendiente a partir de dos puntos es: 
 

A continuación se muestra la implementación del enfoque anterior: 

// C++ program for slope of line
#include <bits/stdc++.h>
using namespace std;
 
// function to find the slope of a straight line
float slope(float x1, float y1, float x2, float y2)
{
    if (x2 - x1 != 0)
        return (y2 - y1) / (x2 - x1);
    return INT_MAX;
}
 
// driver code to check the above function
int main()
{
    float x1 = 4, y1 = 2;
    float x2 = 2, y2 = 5;
    cout << "Slope is: " << slope(x1, y1, x2, y2);
    return 0;
}

// Java program for slope of line
import java.io.*;
 
class GFG {
    static float slope(float x1, float y1, float x2,
                       float y2)
    {
        if (x2 - x1 != 0)
            return (y2 - y1) / (x2 - x1);
        return Integer.MAX_VALUE;
    }
    public static void main(String[] args)
    {
        float x1 = 4, y1 = 2;
        float x2 = 2, y2 = 5;
        System.out.println("Slope is "
                           + slope(x1, y1, x2, y2));
    }
}

# Python program for slope of line
def slope(x1, y1, x2, y2):
    if(x2 - x1 != 0):
      return (float)(y2-y1)/(x2-x1)
    return sys.maxint
 
 
# driver code
x1 = 4
y1 = 2
x2 = 2
y2 = 5
print "Slope is :", slope(x1, y1, x2, y2)

using System;
 
public static class GFG {
    // C# program for slope of line
 
    // function to find the slope of a straight line
    public static float slope(float x1, float y1, float x2,
                              float y2)
    {
        if (x2 - x1 != 0F) {
            return (y2 - y1) / (x2 - x1);
        }
        return int.MaxValue;
    }
 
    // driver code to check the above function
    internal static void Main()
    {
        float x1 = 4F;
        float y1 = 2F;
        float x2 = 2F;
        float y2 = 5F;
        Console.Write("Slope is: ");
        Console.Write(slope(x1, y1, x2, y2));
    }
}
