$Slope of given line is m = - 3$ $color(brown)("Slope of given line is " m = -3$

$(x_{1}, y_{1}) = (1, 2), (x_{2}, y_{2}) = (3, - 4)$ $(x_1,y_1) = (1,2), (x_2, y_2) = (3,-4)$

$S l o p e m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}$ $Slope " " m = (y_2 - y_1) / (x_2 - x_1)$

$m = \frac{- 4 - 2}{3 - 1} = - \frac{6}{2} = - 3$ $m = (-4-2) / (3-1) = -6/2 = -3$

How do you find the slope for (1,2)(1,2)(1,2) (3,-4)(3,−4)(3,-4)?
