The parametric equations of the line are given by:

x(t) = 3 + 5t

y(t) = -1 + 3t

z(t) = -8 + 3t

---------------------------

A line passing through the point (x_0, y_0, z_0) and being parallel to a vector ai + bj + ck has parametric equations given by:

x(t) = x_0 + at

y(t) = y_0 + bt

z(t) = z_0 + ct

---------------------------

Point (3, -1, -8) means that x_0 = 3, y_0 = -1, z_0 = -8

.Parallel to vector 5i + 3j + 3k means that a = 5, b = 3, c = 3

Thus

x(t) = 3 + 5t

y(t) = -1 + 3t

z(t) = -8 + 3t
