Vectors, Parametric equation form of a line - IB Maths HL


The Parametric form for the equation of a straight line is :








where is a position vector (a point on the line)

and is a direction vector ( a vector parallel to the line)

is a real number parameter.


Therefore for your question we have that the parametric equation form is









Hope these help!!
