The slope $= 3$ $=3$

The coordinates are:
$(3, 4) = (x_{1}, y_{1})$ $(3,4) = color(blue)((x_1 , y_1)$

$(2, 1) = (x_{2}, y_{2})$ $(2,1) = color(blue)((x_2 , y_2)$

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

$= \frac{1 - 4}{2 - 3}$ $= (1-4) / (2-3)$

$= \frac{- 3}{- 1}$ $= (-3) / (-1)$

$= 3$ $=3$

The slope $= 3$ $=3$
