Category:Equation of Straight Line in Space/Two-Point Form

This category contains pages concerning Equation of Straight Line in Space/Two-Point Form:

Let $\LL$ be a straight line embedded in a cartesian $3$-space passing through the points $\tuple {x_1, y_1, z_1}$ and $\tuple {x_2, y_2, z_2}$.

$\LL$ is expressed in two-point form by the equation:

$\dfrac {x - x_1} {x_2 - x_1} = \dfrac {y - y_1} {y_2 - y_1} = \dfrac {z - z_1} {z_2 - z_1}$
