#slope = 1/2 #
Explanation:
To find the gradient (slope ) of a line joining 2 points use the 'gradient formula' :
# m = (y_2 - y_1 )/(x_2 - x_1) # where m represents the slope and
#(x_1 , y_1 ) , (x_2 , y_2 )# are the coordinates of the 2 points.
let
#(x_1 , y_1 ) = ( 3 , 7 ) and (x_2 , y_2 ) = (7 , 9 )# for this question.Evaluating: m =
# (9 - 7 )/(7 - 3 ) = 2/4 = 1/2 #
