Question

Create a function make_line, whose input is the list ? of coordinates (?,?) , and whose output is the equation of a line (in the variable ? ) with slope ? , going through ? .

from sympy import *
x = symbols('x')

def make_line(s,p):
# type your answer here

Answer 1

from sympy import *

x = symbols('x')

def make_line(s,p):

    # equation of line passing through point (a,b) with slope s is
    # y = s(x - a) + b

    # X coordinate is p[0] and y coordinate is p[1]
    a = p[0]
    b = p[1]

    return s*(x - a) + b


y = (make_line(2,[4,7]))

print("y =",y)

I have added comments to explain the logic behind the code. Please play around with different values of p and s to get a sense of how the code works.

The output is-
