Answer

The point slope form is $y+2=\frac{1}{5}(x+3)$.

Work Step by Step

The given points are $(x_1,y_1)=(-3,-2)$ and $(x_2,y_2)=(2,-1)$ Slope $\Rightarrow m =\frac{y_2-y_1}{x_2-x_1}$ Substitute all the values. $\Rightarrow m =\frac{-1-(-2)}{2-(-3)}$ Simplify. $\Rightarrow m =\frac{-1+2}{2+3}$ $\Rightarrow m =\frac{1}{5}$ The point-slope form. $\Rightarrow y-y_1=m(x-x_1)$ Substitute all the values. $\Rightarrow y-(-2)=\frac{1}{5}(x-(-3))$ Simplify. $\Rightarrow y+2=\frac{1}{5}(x+3)$ Hence, the point slope form is $y+2=\frac{1}{5}(x+3)$.
