(Geometry: distance of two points) Write a program that prompts the user to enter  two points (x1, y1) and (x2, y2) and displays their distance between them.The formula for computing the distance is  √ (x2 - x1)²+ (y2 - y1)² . Note that you  can use pow(a, 0.5) to compute √a.  #Beginner In gcc c++ compiler using namespace std; #include<iostream> #include<cmath> using namespace std; int main() { float x1,y1,x2,y2; cout<< "Enter x1 and y1 :" ; cin>>x1>>y1; cout<< "Enter x2 and y2 :" ; cin>>x2>>y2; float distance=pow((pow(x2-x1,2))+pow(y2-y1,2),0.5); cout<< "The distance between the two points is :" <<distance; return 0; } copy Output Enter x1 and y1 :1 9 Enter x2 and y2 :3 -5 The distance between the two points is :14.1421 [Program finished] Need of Programmer Need of Programmer

Write a program that prompts the user to enter the coordinates of two points (x1, y1) and (x2, y2), and displays the slope of the line that connects the two points. The formula of the slope is (y2 - y1)/(x2 - x1).

(Slope of a line) Write a program that prompts the user to enter the coordinates of two  points (x1, y1) and (x2, y2), and displays the slope of the line that connects the two  points. The formula of the slope is (y2 - y1)/(x2 - x1).  #Beginner In gcc c++ compiler using namespace std; #include<iostream> using namespace std; int main() { float x1,y1,x2,y2; cout<< "Enter the coordimnates for two points :\n" ; cout<< "x1 and y1 :" ; cin>>x1>>y1; cout<< "x2 and y2 :" ; cin>>x2>>y2; float slope; slope=(y2-y1)/(x2-x1); cout<< "The slope for te line that connects two points\n(" << "x1=" <<x1<< ",y1=" <<y1 << ",x2=" <<x2<< ",y2=" <<y2 << ") is " <<slope; return 0; } copy Output Enter the coordimnates for two points : x1 and y1 :1 2 x2 and y2 :7 5 The slope fo...
