Determine whether the points lie on straight line
A(2, 4, 2) B(3, 7, -2) C(1, 3, 3)
Homework Equations
The Attempt at a Solution
I've looked up at the equation for lines in three dimension, and it appears to be
x=x_0+at
y=y_0+bt
z=z_0+ct
i tried to take the x y z for A and B and try to solve for a, b, c. Then if the same a, b, c work for BC, then ABC is on a line. That is my thought, but i can't manage to do the first part. I don't know how to use the information given and the equations to start with...
Anyone please help me with this. This is my first time working with 3-dimensional coordinate system...
