Find the vector equation of a line passing through (2, –1, 1) and parallel to the line whose equations are

Answer :

the direction ratios of the line

Are‹


So in this question the direction ratios of the given line are ‹2, 7, –3›


So the vector equation of


Here


vector equation of a line is



so the vector equation of the line is



Here x = 2 + 2, y = –1 + 7, z = 1–3



Hence the cartesian equation of the above line is
