Sinceyou are lookingfor the slopeof a parallelline, it will havethe sameslopeas the line in the diagram.
First identifythe slopeof the line given,and selectthe answerwith that slope.You can use the slopeformula
to find its value.Pick two pointson the line. For example,(-1,5)and (3,1).
The slopeof the line in the diagramis The answeris B.
Slopesof PerpendicularLines
Parallellines havethe sameslope.Thereis also a mathematicalrelationshipfor the slopesof perpendicular
lines.
PerpendicularLine SlopeTheoremThe slopesof perpendicularlines will be theopposite
reciprocalof eachother.
