IB Mathematics HL – Vectors, Vector equation of a line 3D

How can we find the vector equation of the line passing through the point (1,4,5) and is parallel to the vector ?

Thanks

IB Mathematics HL – Vectors, Vector equation of a line 3D

The vector equation of a line is given by the following formula

where a is a position vector of the line (i.e. a point on the line) , b is a direction vector (i.e. a vector parallel to the line) and is a real number parameter.

So the vector equation of the line is given by the formula

Hope these help!
