IB Mathematics SL – Vectors, Vector equation of a line



How can we find the vector equation of the line passing through the point (2,7) and is parallel to the vector ?



Thanks
Jack

IB Mathematics SL – Vectors, Vector equation of a line

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! :D :D
