Find the slope of the line that is parallel and perpendicular to the line through the pair of points

You use the same slope for a parallel equation, but the reciprocal of the slope for a perpendicular equation. 

Ex) x=2 for parallel 
      x=-2 for perpendicular 

That is one of the main things you must do, but after you must find the slope from your pair of points using the slope formula. 

Hope this helped:)

The range would be 13 because you’re finding the difference

Solution: beginning of the unit = - 2end of the unit = beginning of the unit + 4end of the unit = - 2 + 4end of the unit = 2final answer: therefore, aila was able to reach 2 ( insert name of unit of measurement ) at the end of the unit.hope this ! : )have a lovely day! < 3
