Final answer:

The parametric equations of the line passing through points (1,4,2) and (3,5,0) are x = 1 + 2t, y = 4 + t, and z = 2 - 2t. The symmetric equations of the line are \(\frac{x-1}{2} = \frac{y-4}{1} = \frac{z-2}{-2}\).

Step-by-step explanation:

To find the parametric equations of the line passing through points (1,4,2) and (3,5,0), we first find the direction vector d by subtracting the coordinates of the first point from the second: d = (3-1, 5-4, 0-2) = (2,1,-2).

The parametric equations are then:

  • x = 1 + 2t
  • y = 4 + t
  • z = 2 - 2t

For the symmetric equations, we use the direction vector and the initial point to form the following equations:

\(\frac{x-1}{2} = \frac{y-4}{1} = \frac{z-2}{-2}\)

Note: When writing the symmetric equation, ensure that each fraction is equal to the parameter t.
