Using Slope Formula

  • Draw two parallel lines. Use the slope formula to demonstrate that they have the same slope.

m=\frac{\Delta y}{\Delta x}=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

 

 

 

 

 

 

 

 

 

 

 

line 1:

m=\frac{0-3}{-2-0}=\frac{-3}{-2}=\frac{3}{2}

line 2:

m=\frac{-1-2}{0-2}=\frac{-3}{-2}=\frac{3}{2}
