The equation of the line passing through point $ \left(\dfrac{ 6479 }{ 10 },~169\right) $, and point $ \left(\dfrac{ 3473 }{ 5 },~\dfrac{ 838 }{ 5 }\right) $ is:
$$ y = - \frac{ 14 }{ 467 } x + \frac{ 439968 }{ 2335 } $$To find equation of the line passing through points $ A(x_A,y_A) $ and $ B(x_B,y_B) $, we use formula:
$$ y - y_A~=~\frac{y_B - y_A}{x_B - x_A}(x-x_A) $$In this example we have:
$$ \begin{aligned} & \left(\dfrac{ 6479 }{ 10 },~169\right) \implies x_A = \frac{ 6479 }{ 10 } ~~\text{and}~~ y_A = 169 \\[1 em] & \left(\dfrac{ 3473 }{ 5 },~\dfrac{ 838 }{ 5 }\right) \implies x_B = \frac{ 3473 }{ 5 } ~~\text{and}~~ y_B = \frac{ 838 }{ 5 } \end{aligned} $$After substituting into the formula, we obtain:
$$ \begin{aligned} y - y_A~&=~\frac{y_B - y_A}{x_B - x_A}(x - x_A) \\[1 em] y - 169~&=~\frac{ \frac{ 838 }{ 5 } - 169 }{ \frac{ 3473 }{ 5 } - \frac{ 6479 }{ 10 } } \left( x - \frac{ 6479 }{ 10 } \right) \\[1 em]y - 169 ~&=~ -\frac{ 14 }{ 467 } \left( x - \frac{ 6479 }{ 10 } \right) \\[1 em]y - 169 ~&=~ -\frac{ 14 }{ 467 }x + \frac{ 45353 }{ 2335 } \\[1 em]y ~&=~ -\frac{ 14 }{ 467 }x + \frac{ 439968 }{ 2335 } \end{aligned} $$
