determine the coordinates of two points on the plane with equation 5x + 4y  3z = 6

let x=0, y=0, then z= 2 > (0,0,2)
let x=1, y=0, then z = 1/3  (1,0,1/3)
let two of the variables be anything you want, then solve for the third. 
Just noticed that you had posted this before and Steve had answered you.
