Point Slope Form

$$y=mx+b$$  

$$m=\frac{y_2-y_1}{x_2-x_1}$$  

$$y-y_1=m\left(x-x_1\right)$$  

$$y-x=m\left(x_1-y_1\right)$$  

$$y+3=\frac{1}{3}\left(x-1\right)$$  

$$y+1=\frac{1}{3}\left(x-3\right)$$  

$$y-3=\frac{1}{3}\left(x+1\right)$$  

$$y-1=\frac{1}{3}\left(x+3\right)$$  

$$y+10=-\frac{4}{3}\left(x-7\right)$$  

$$y-10=-\frac{4}{3}\left(x+7\right)$$  

$$y+6=-\frac{3}{4}\left(x-4\right)$$  

$$y+6=-\frac{4}{3}\left(x-4\right)$$  

$$y+10=-\frac{4}{3}\left(x-4\right)$$  

$$y-3=\left(x-2\right)$$  

$$y+3=\left(x+2\right)$$  

$$y-3=-\left(x+2\right)$$  

$$y+3=-\left(x-2\right)$$
