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

from numpy import ones,vstack
from numpy.linalg import lstsq
points = [(1,5),(3,4)]
x_coords, y_coords = zip(*points)
A = vstack([x_coords,ones(len(x_coords))]).T
m, c = lstsq(A, y_coords)[0]
print("Line Solution is y = {m}x + {c}".format(m=m,c=c))

but really your method should be fine ...
