The slope is #1#.

Explanation:

The slope #m# of a line through two points #(x_1, y_1)# and #(x_2, y_2)# is given by dividing the change in #y# by the change in #x# as described by the formula:

#m = (Delta y)/(Delta x) = (y_2-y_1)/(x_2-x_1)#

In our example, #(x_1, y_1) = (-6, -15)# and #(x_2, y_2) = (4, -5)#, giving us:

#m = (-5-(-15))/(4-(-6)) = 10/10 = 1#
