1232. Check If It Is a Straight Line

https://leetcode.com/problems/check-if-it-is-a-straight-line

Description

You are given an array coordinates, coordinates[i] = [x, y], where [x, y] represents the coordinate of a point. Check if these points make a 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

Constraints:

• 2 <= coordinates.length <= 1000

• coordinates[i].length == 2

• -10^4 <= coordinates[i][0], coordinates[i][1] <= 10^4

• coordinates contains no duplicate point.
