Position vector of any point on the line
Position vector of a fixed point on the line
Direction vector of the line
Scalar parameter
They are equivalent and represent the same line
Eliminate λ\lambdaλ from the parametric equations
a\mathbf{a}a is a fixed point on the line, b\mathbf{b}b is direction vector
Not substituting solutions back to check consistency
