In this task, you are required to write a program that represents 2D Lines in the cartesian space. The program consists of three files: the header file (Line. h), the class file (Line. cpp) and the test file (Main. cpp). You are only required to complete the code in Line. cpp file. We already wrote the other two files. To understand what you need to do, read the codes in below. Sample Testcase 0:

Input:

-1 3 -3 9 1

Output:

Start point: (-1,3)
End point: (-3,9)
Slope = -3
Is line horizontal? no
Is line vertical? no
Does the line or its extension pass through the origin? yes
New end point after mirroring wrt x-axis: (-3,-3)

Sample Testcase 1:

Input:

2.5 4.5 3.5 4.5 1

Output:

Start point: (2.5,4.5)
End point: (3.5,4.5)
Slope = 0
Is the line horizontal? yes
Is the line vertical? no
Does the line or its extension pass through the origin? no
New end point after mirroring wrt x-axis: (3.5,4.5)

Sample Testcase 2:

Input:

7.2 3.1 22 12.6 -1

Output:

Start point: (7.2,3.1)
End point: (22,12.6)
Slope = 0.641892
Is the line horizontal? no
Is the line vertical? no
Does the line or its extension pass through the origin? no
New end point after mirroring wrt y-axis: (-7.6,12.6)

Sample Testcase 3:

Input:

1 4 1 19 1

Output:

Start point: (1,4)
End point: (1,19)
Slope = inf
Is the line horizontal? no
Is the line vertical? yes
Does the line or its extension pass through the origin? no
New end point after mirroring wrt y-axis: (1,-11)
