Question
The cartesian equations of a line are 
Find a vector equation for the line.
Solution
The cartesian equations of line are
∴ line passes through (5, - 4, 6) and has direction-ratios 3, 7, 2
Let
be the position vector of any point on the given line
∴ the vector equation of line is
or
where λ is a parameter.
