A line is defined as the set of alligned points on the plane with a point, P, and a directional vector, .

If P(x_{1}, y_{1}) is a point on the line and the vector
has the same direction as
, then
equals
multiplied by a scalar unit:

A line passes through point A = (−1, 3) and has a directional vector with components (2, 5). Determine the equation of the vector.

Write the vector equation of the line which passes through the points A = (1, 2) and B = (−2, 5).
