The slope for the coordinates $= 0$ $=0$

$(2, - 5) = x_{1}, y_{1}$ $(2,-5) = color(blue)(x_1, y_1)$

$(- 10, - 5) = x_{2}, y_{2}$ $(-10,-5) = color(blue)(x_2, y_2)$

The slope is calculated using formula:
Slope $= \frac{y_{2} - y_{1}}{x_{2} - x_{1}}$ $=color(blue)((y_2 - y_1) / (x_2 - x_1)$

$= \frac{- 5 - (- 5)}{- 10 - 2}$ $= (-5 - (-5)) / (-10 - 2)$

$= \frac{- 5 + 5}{- 10 - 2}$ $= (-5 + 5) / (-10 - 2)$

$= \frac{0}{- 12}$ $= 0 / (-12)$

$= 0$ $=0$
