Answer :

Given: line passes through (1, -2, 3) and is parallel to the line

To find: equation of line in vector and Cartesian form

Formula Used: Equation of a line is

Vector form:

Cartesian form:

where is a point on the line and is a vector parallel to the line.


Since the line (say L1) is parallel to another line (say L2), L1 has the same direction ratios as that of L2


Since the equation of L2 is


Vector form of the line is:

Cartesian form of the line is:
