[tex]\bf (\stackrel{x_1}{3}~,~\stackrel{y_1}{2})\qquad (\stackrel{x_2}{-4}~,~\stackrel{y_2}{1}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{1-2}{-4-3}\implies \cfrac{-1}{-7}\implies \cfrac{1}{7}[/tex]

Hello!

Step-by-step explanation:

Slope: [tex]\frac{Y^2-Y^1}{X^2-X^1}=\frac{rise}{run}[/tex]

[tex]\frac{1-2=-1}{(-4)-3=-7}=\frac{-1}{-7}=\frac{1}{7}[/tex]

Therefore, the slope is 1/7

Answer is 1/7

Hope this helps!

Thanks!
