Question

1（a)   

Write a python program using a function name slope(x1, y1, x2, y2) that returns the slope of the line through the points (x1, y1) and (x2, y2).

1（b）

For problem 1(a), write a python program using a function name Euclidean_dist(x1, y1, x2, y2) which will calculate and return the Euclidean distance between the points (x1, y1) and (x2, y2).

Answer 1

def slope(x1, y1, x2, y2):
    return (y2-y1)/(x2-x1)

def Euclidean_dist(x1, y1, x2, y2):
    return ((x1 - x2) ** 2 + (y1 - y2) ** 2) ** 0.5
