I'm trying to prepare for my calculus 3 class coming up this fall and doing some practice problems. I'm having a hard time visualizing some of these 3D coordinates.
$D(0,-5,5)$ $E(1,-2,4)$ $F(3,4,2)$
The answer is yes and I drew out the coordinates to try and understand why this answer is a yes and although I can't 'see' why it's a yes I imagine it is because all the points appear to be on the same plane, yz?
Is this correct and do you have any suggestions that can help visualizing or is it just a matter of practice?
