I am attempting to solve a question a question of stokes theorm, but i have got stuck with this question in which i have to first find the equation of a line passing through three points.

The points are (3,0,0),(0,3/2,0),(0,0,3).

I remember doing something like this in calculus class but i dont remember how exactly to go about such problems.

Someone please help me out with this.
