c++ program to find slope of a graph:

#include <iostream>
using namespace std;
int main()
{
    float x1,x2,y1,y2;
    double slope;
    cout<<" Enter value of x1 = \n";
        cin>>x1;
    cout<<"Enter value of x2 = \n";
    cin>>x2;
    cout<<"Enter value of y1 = \n";
    cin>>y1;
    cout<<"Enter value of y2 = \n";
    cin>>y2;
    {
        slope=(y2-y1)/(x2-x1);
        cout<<"The slope is = "<<slope;
    }
        return 0;
}
