#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 #
