The distance method uses the square root function under the hood. Also the length won`t be changed because the points are fixed. It is better to store the length as an instance variable and use lazy initialization.
def length
@length ||= begins_at.distance ends_at
end| def to_straight_line | ||
| a = ends_at.y - begins_at.y | ||
| b = begins_at.x - ends_at.x | ||
| c = -begins_at.x * ends_at.y + begins_at.y * ends_at.x |
