Slope of the line $m = 5$ $color(chocolate )(m = 5)$

Slope of a line knowing two points on it is given by

Slope $m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}$ $m = (y_2 - y_1) / (x_2-x_1)$

Given : $(x_{1}, y_{1}) = (3, 15), (x_{2}, y_{2}) = (1, 5)$ $(x_1,y_1) = (3,15), (x_2,y_2) = (1,5)$

Slope $= m = \frac{5 - 15}{1 - 3} = \frac{- 10}{- 2} = 5$ $= m = (5-15) / (1-3) = (-10)/(-2 )= color (chocolate)(5$
