Question 171407
ok lets find the slope first m=rise/run or change in y/change in x.
:
m=3-7/0-5=4/5
:
so any line parallel to a line thru these two point must have the same slope of {{{m=4/5}}}.  Any line perpendicular to a line passing through these point have to have the - inverse of the slope 4/5 which is {{{m=-5/4}}}
