Equation of a Line Through two Points in 3 D
\( \)\( \)\( \)A calculator and solver to find the equation of a line in vector, parametric and symmetric forms is presented. An unlimited number of examples may be generated interactively along with their solutions. Below is shown a line through two points \( P(x_p,y_p,z_p) \) and \( Q(x_q,y_q,z_q) \).
Three forms of the equation of the line:
STEP 1: Find the components of vetor \( \vec {PQ} \) .
STEP 2: Write Equation in Vector form.
STEP 3: Write Equation in Parametric form.
STEP 4: Write Equation in Symmetric form.
