#-7/13 #
Explanation:
To find 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 )color(black)(" are coords of 2 points ") # let
# (x_1 , y_1 ) = (5 , -6 )color(black)(" and ") (x_2,y_2) = (-8 , 1 )# substitute into gradient formula :
#rArr m = (1-(-6))/(-8-5) = 7/-13 = -7/13 #
