The vector equation of the x-axis is given by

Vector equation need a fixed point and a parallel vector

For x-axis fixed point can be anything ranging from negative to positive including origin

And parallel vector is î

Equation would be λ î

A line passes through the point
A(-2, 4, -5) and is parallel to the line The vector equation of the line is

The coordinates of the point where the line through the points A(5, 1, 6) and B(3, 4, 1) crosses the yz-plane is

The Cartesian equations of a lines are What is its vector equation?

The angle between two lines having direction ratios 1, 1, 2 and 4 is
