OpenStudy (karatechopper):

well there is no and..

OpenStudy (karatechopper):

slope=y1-y2/x1-x2

OpenStudy (anonymous):

ok can u just show me how to figure it out for this specific question

OpenStudy (karatechopper):

ok

OpenStudy (karatechopper):

10+9/-10-7 19/-17 thts ur slope^

OpenStudy (karatechopper):

perpendicualr is opposite of reciprocal.. therefore ur slope is now 17/19 now u have equation m=17/19+b

OpenStudy (karatechopper):

now u pick a point
