X = [-15, 10, 3] + r * [5, -2, 0]
Spurpunkte
[-15, 10, 3] + r * [5, -2, 0] = [0, y, z] --> y = 4 ∧ z = 3 ∧ r = 3 --> [0, 4, 3]
[-15, 10, 3] + r * [5, -2, 0] = [x, 0, z] --> x = 10 ∧ z = 3 ∧ r = 5 --> [10, 0, 3]
[-15, 10, 3] + r * [5, -2, 0] = [x, y, 0] --> Keine Lösung, da die Gerade parallel zur x-y-Ebene verläuft.
