#-4#

Explanation:

The slope is essentially the gradient of the line:

The formulaic approach to find the gradient of the a line with two given points: #(x_1,y_1)# and #(x_2,y_2)# is

#\frac{y_2-y_1}{x_2-x_1]#

Therefore plugging in the values o the points gives us:

#\frac{5--7}{1-4}=-\frac{12}{3}=-4#
