You are given an array, coordinates, where each element in coordinates[i] $= [x, y]$ represents the coordinates of a point on a $\text{2D}$ plane. Determine whether all the points in the array lie on a single straight line in the XY plane.

Constraints:

• $2 \leq$ coordinates.length $\leq 1000$

• coordinates[i].length $== 2$

• $-10^4 \leq$ coordinates[i][0], coordinates[i][1] $\leq 10^4$

• coordinates do not contain any duplicate points.
