Answer:

Vector equation:

(4 + 6t, 2.1 + 4t, 3.1 - 2t)

Parametric equations:

x(t) = 4 + 6t

y(t) = 2.1 + 4t

z(t) = 3.1 - 2t

Step-by-step explanation:

The line is parallel to the vector 3i + 2j − k.

So the vector of this line is a multiple of this vector, so i will use 6i + 4j - 2k.

The line goes through the point (4, 2.1, 3.1).

So the parametric equations are:

x(t) = 4 + 6t

y(t) = 2.1 + 4t

z(t) = 3.1 - 2t

The vector equation is:

(4 + 6t, 2.1 + 4t, 3.1 - 2t)
