线的斜率与具有给定斜率的线平行

给定一个整数m ，它是一条线的斜率，任务是找到与给定线平行的线的斜率。
例子：

Input: m = 2 
Output: 2
Input: m = -3 
Output: -3 
 

方法：

设P和Q为两条平行线，分别具有等式y = m1x + b1和y = m2x + b2 。这里m1和m2分别是线的斜率。现在，由于线是平行的，所以它们没有任何相交点，因此将没有线的解决方案系统。因此，让我们尝试求解方程式，

For y, m1x + b1 = m2x + b2 
m1x – m2x = b2 – b1 
x(m1 – m2) = b2 – b1 
The only way there can be no solution for x is for m1 – m2 to be equal to zero. 
m1 – m2 = 0 
This gives us m1 = m2 and the slopes are equal. 
 

下面是上述方法的实现：

C++

// C++ implementation of the approach
#include 
using namespace std;
 
// Function to return the slope
// of the line which is parallel to
// the line with the given slope
double getSlope(double m)
{
    return m;
}
 
// Driver code
int main()
{
    double m = 2;
    cout << getSlope(m);
 
    return 0;
}

Java

// Java implementation of the approach
class GfG
{
     
// Function to return the slope
// of the line which is parallel to
// the line with the given slope
static double getSlope(double m)
{
    return m;
}
 
// Driver code
public static void main(String[] args)
{
    double m = 2;
    System.out.println(getSlope(m));
}
}

Python3

# Python3 implementation of the approach
 
# Function to return the slope
# of the line which is parallel to
# the line with the given slope
def getSlope(m):
 
    return m;
 
# Driver code
m = 2;
print(getSlope(m));

}
 
// Driver code
