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 + λb, 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:
