# What is the slope of the line passing through the following points:  (-3,-6) ; (18,8) ?

 2/3

#### Explanation:

To calculate the gradient (slope) of a line passing through 2 points , use the$\textcolor{b l u e}{\text{ gradient formula }}$

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

where $\left({x}_{1} , {y}_{1}\right) , \left({x}_{2} , {y}_{2}\right) \text{ are the coords of the 2 points }$

here let (x_1,y_1) =(-3 , -6) and" (x_2,y_2) = (18 , 8)

rArr m =( (8-(-6))/(18-(-3)) = 14/21 = 2/3 #
