Answer:
Unless there is more to the question than c = 2 because 30 /5 = 6 and if c is 3 than 3 = 6 so simplify if needed.
The vector equation of the line through the origin perpendicular to the plane is
.. (x, y, z) = t(2, 3, -1)
so the point of interest will satisfy
.. 2(2t) +3(3t) -(-t) = -3
.. 14t = -3
.. t = -3/14
and its coordinates are (x, y, z) = (-3/7, -9/14, 3/14)
4 + 3 over 4. 9- 2 over 3
4- 9 ➡ -5
3 over 4- 2 over 3
9 over 12- 8 over 12 ➡ 1 over 12
-5 + 1 over 12 ➡-4 and 11 over 12
Therefore, your answer would have to be ➡ 4 and 11 over 12
