Description

You are given an array of 2D coordinates, where coordinates[i] = [x, y] represents a point. Determine whether all the given points lie on the same straight line in the XY plane.

Example 1:

Input: coordinates = [[1,2],[2,3],[3,4],[4,5],[5,6],[6,7]]

Output: true

Example 2:

Input: coordinates = [[1,1],[2,2],[3,4],[4,5],[5,6],[7,7]]

Output: false
