The rule of the slope of the line is


m=(y2-y1)/(x2-x1)

(x1, y1) and (x2, y2) are two points on the line

Since the line passes through points (-1, 8) and (12, -5), then

x1 = -1 and y1 = 8

x2 = 12 and y2 = -5

Substitute theses values in the rule above to find m


m=(-5-8)/(12--1)=(-13)/(12+1)=(-13)/(13)=-1

The slope of the line is -1
