slope = (change in #y#) / (change in #x#)

More formally, if a line passes through two points #(x_1, y_1)# and #(x_2, y_2)#, then the slope #m# of the line is given by the formula:

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

In the case of the points #(4, 9)# and #(1, 6)#, we get:

#m = (6 - 9) / (1 - 4) = (-3)/(-3) = 1#
