Question

Find three points on this plane:
[x, y, z ]= [3, 4, -1] +s [1, 1, -4 ] +t [2, -5, 3 ]

Answer 1

Have you considered selecting three values for s and t?

Answer 2

Just any random numbers to substitute and the come up with the answer like that ?

Answer 3

Yep. Furthermore, make the calculations idiot proof by selecting simple numbers. I would use (s,t)=(0,0),(0,1),(1,0) to make the calculations as simple as possible..

Answer 4

Random is not necessary. You can be arbitrary.

Answer 5

Thank you ! :)

Answer 6

No sweat. Do math every day.
