Method to return the equation of a straight line given two points

Question

I have a class Point, consisting of a point with x and y coordinates, and I have to write a method that computes and returns the equation of a straight line joi

Answer 1

I think you are making pretty advanced code, but you are making it complicated. Here is a function that can do that:

from decimal import Decimal


def lin_equ(l1, l2):
    """Line encoded as l=(x,y)."""
    m = Decimal((l2[1] - l1[1])) / Decimal(l2[0] - l1[0])
    c = (l2[1] - (m * l2[0]))
    return m, c

# Example Usage:
lin_equ((-40, 30,), (20, 45))

# Result: (Decimal('0.25'), Decimal('40.00'))
