Hey! :)
To find the slope of a line, well use the point slope formula: [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
So all we need to do is plug in those values in that equation
[tex]\frac{y_2-y_1}{x_2-x_1}\\\frac{6-3}{12-(-6)}\\ \frac{3}{18}\\ \frac{1}{6}[/tex]
So the slope = 1/6
Let me know if you need anything further explained! :)
