In this lesson on vectors, we’ll be looking at how to find the vector equation of lines.

## Format of Vector Equation of line:

The vector equation of the line is written as **r** = **a** + λ**b**, where λ∈ ℝ, **a** is a position vector that lies on the line, and **b** is any direction vector parallel to the line.

## Parametric Equation of line

The parametric equation of a line takes the form:

x = a₁ + λb₁

y = a₂ + λb₂

z = a₃ + λb₃

## Cartesian Equation of line

The cartesian equation of a line takes the form:
