# Python: Check whether two given lines are parallel or not

## Python Basic - 1: Exercise-103 with Solution

Write a Python program to check whether two given lines are parallel or not.
Note: Parallel lines are two or more lines that never intersect. Parallel Lines are like railroad tracks that never intersect.
The General Form of the equation of a straight line is: ax + by = c
The said straight line is represented in a list as [a, b, c]
Example of two parallel lines:
x + 4y = 10 and x + 4y = 14

Sample Solution:

Python Code:

``````def parallel_lines(line1, line2):
return line1/line1 == line2/line2
#2x + 3y = 4, 2x + 3y = 8
print(parallel_lines([2,3,4], [2,3,8]))
#2x + 3y = 4, 4x - 3y = 8
print(parallel_lines([2,3,4], [4,-3,8]))
``````

Sample Output:

```True
False
```
