Use the standard formula for slope to find #m = -1#.

Explanation:

The slope #m# of a line passing through points #(x_1, y_1)# and #(x_2, y_2)# is given by the formula:

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

Let #(x_1, y_1) = (-1, -1)# and #(x_2, y_2) = (4, -6)#

Then

#m = (y_2 - y_1) / (x_2 - x_1) = (-6 - (-1)) / (4 - (-1)) = -5 / 5 = -1#
