Two points on the graph are (6,-2) and (-6,-1)
Using these two points we find the slope
The formula for slope using two points
[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
(6,-2) x1=6, y1= -2 and (-6,-1) x2=-6, y2= -1
Replace all the values and find out slope
[tex]\frac{-1-(-2)}{-6-6}[/tex]
[tex]\frac{1}{-12}[/tex]
slope = [tex]\frac{-1}{12}[/tex]
