    Line Plane Point
AI Thread Summary
To determine if the point (6,0,-2) lies on the line defined by the equations x = 4-2t, y = 3+5t, and z = 7+4t, one should substitute the coordinates into the equations and solve for t. The attempt revealed that substituting the point yields different values of t, specifically t = -1, -3/5, and -9/4. Since these values do not match, it confirms that the point does not lie on the line. The conclusion drawn is that the point (6,0,-2) is indeed not on the line.

Homework Statement


This is the point:

(6,0,-2)

Homework Equations


x = 4-2t
y = 3+5t
z = 7+4t

The Attempt at a Solution



Do I just plug in the points and see if I get matching values of t? If not, how do I go about this?

What is stopping you from just going ahead and trying it out for yourself?
 
I did try it. I'm asking if this is the right way to do this. I do not have any answers for this problem. Can you please tell me if that is the right way to do this?

It is the right way to see if the given point lies on the line. What is your answer?

t = -1, -3/5, -9/4

So the point does not lie on the line?
