The equation of the line passing through point $ \left(67.9825,~1\right) $, and point $ \left(67.9825,~0\right) $ is:
$$ x-67.9825=0 $$In this example we have:
$$ \begin{aligned} & \left(67.9825,~1\right) \implies \color{blue}{x_A = 67.9825} ~~\text{and}~~ y_A = 1 \\[1 em] & \left(67.9825,~0\right) \implies \color{blue}{x_B = 67.9825} ~~\text{and}~~ y_B = 0 \end{aligned} $$Since, $ x_A = x_B $ the equation of the line is:
$$ x = x_A $$In this example this is:
$$ x = 67.9825 $$
