### Explanation:

To find the slope (m) of the line passing through the two given points, use the formula:

\[ m = \frac{(Y_2 - Y_1)}{(X_2 - X_1)} \]

Where:
- \((X_1, Y_1)\) = Coordinates of station Shore = \((653387.06, 395027.52)\)
- \((X_2, Y_2)\) = Coordinates of station Rock = \((651991.62, 391634.06)\)

Calculate:

\[ m = \frac{(391634.06 - 395027.52)}{(651991.62 - 653387.06)} \]

To find the y-intercept (b), use the equation of the line in slope-intercept form:

\[ Y = mX + b \]

Select either point to plug in values for Y, X, and the calculated slope (m) to solve for b.
