Which of the following planes is the equation for the plane with an x-intercept (2,0,0), a y-intercept at (0,-3,0), and is parallel to the z-axis?
a) 3x-2y-6 = 0
b) 2x-3y+z-6=0
c) 3x-2z-6 = 0
d) z=-6
Hint: You can try substituting in the coordinates point and try to see which one fits all the cases.
