i think its 1/2 but im not shure

OpenStudy (anonymous):

\[\frac{ y _{2}-y _{1} }{ x _{2}-x _{1}}\]

OpenStudy (anonymous):

(5, 10)\[(x_{1}, y _{1})\](0, 0) \[(x _{2}, y _{2})\]

OpenStudy (anonymous):

so m= 2

OpenStudy (anonymous):

yup

OpenStudy (anonymous):

and perpendicular is oposite

OpenStudy (anonymous):

so 1/2

OpenStudy (anonymous):

its the opposite inverse correct

OpenStudy (anonymous):
