Question

using C++ please

Given two points (x1, y1) and (x2, y2), the slope of the line running through those points is defined as rise / run, or

Recall that the slope is defined as rise / run, or (y2-y1) / (x2-x1). In the previous exercise you were allowed to assume that the run would never be 0, thus avoiding division by 0. This assumption is no longer true.

Since division by 0 is mathematically undefined, your task in this assignment is to check for a run == 0.0, and output “Slope: undefined” in this case. Example: given the inputs

Your program should now output

Explanation / Answer

Here is your code

#include <iostream>

   using namespace std;
  
int main()
{
  
   float x1,x2,y1,y2;    // declare variables for first and second points
   float slop;           // for storing slop
  
   cout<<"Enter X1, Y1 ";
   cin>>x1>>y1;               // take input from user first point
   cout<<"Enter X2, Y2 ";
   cin>>x2>>y2;               // take input from user second point
  
   cout<<"("<<x1<<","<<y1<<") ";
   cout<<"("<<x2<<","<<y2<<") ";
   if(x2-x1 == 0)        // check for divisible by zero
   {
       cout<<"slop : undifined";     // if zero print undifined
   }
   else                          // else find slop and print it
   {
         slop = (y2-y1)/(x2-x1);
       cout<<"slop : " << slop;
   }
  
   return 0;
}
