Slope of the line $\textcolor{c h o c o l a t e}{m = 5}$

Explanation:

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

Slope $m = \frac{{y}_{2} - {y}_{1}}{{x}_{2} - {x}_{1}}$

Given : $\left({x}_{1} , {y}_{1}\right) = \left(3 , 15\right) , \left({x}_{2} , {y}_{2}\right) = \left(1 , 5\right)$

Slope = m = (5-15) / (1-3) = (-10)/(-2 )= color (chocolate)(5
