$5x-2y-21=0$

Equation of the straight line passing through the points $(11, 17)\equiv(x_1, y_1)$ & $(23, 47)\equiv(x_2, y_2)$ is given as

$y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)$

$y-17=\frac{47-17}{23-11}(x-11)$

$y-17=\frac{5}{2}(x-11)$

$2y-34=5x-55$

$5x-2y-21=0$

What is the equation of the line passing through (11,17)(11,17) and (23,47)(23,47)?
