# 2/3

#### Explanation:

To calculate the gradient (slope) of a line passing through 2 points , use the

# color(blue)(" gradient formula ")#

# m = (y_2 - y_1)/(x_2 - x_1) # where

#(x_1 , y_1) , (x_2, y_2)" 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 #
