.

The slope of the line is the ratio of y-increment to x-increment:


                    slope = .


delta_y = -7 - 3 = - 10.

delta_x = 4 - (-1) = 4 + 1 = 5.

slope =  = -2.


Answer.  The slope = -2.

Solved.

The lesson to learn from this solution: The slope of the line is the ratio of y-increment to x-increment.
