What is the Point-Slope Form: Slope=4 (2, 3)

• $y-4=2\left(x-3\right)$

• $y-2=4\left(x-3\right)$

• $y-3=4\left(x-2\right)$

• $y+3=4\left(x+2\right)$

What is the Point-Slope Form: Slope=3/2  (1, -4)

•  $y-\frac{3}{2}=1\left(x-4\right)$ 

•  $y+4=\frac{3}{2}\left(x-1\right)$ 

•  $y-4=\frac{3}{2}\left(x+1\right)$ 

•  $y-1=\frac{3}{2}\left(x+4\right)$
