# 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 #
