Question

anonymous · Answer

this is written in point slope form.  the slopes must be reciprocals with the opposite sign...

anonymous · Answer

to be perpendicular

anonymous · Answer

what is the reciprocal of 2 or 2/1?

anonymous · Answer

then take the opposite sign.

anonymous · Answer

point slope form is y-y1=m(x-x1)....look for the value where you see the m.

anonymous · Answer

?

anonymous · Answer

umm

anonymous · Answer

im confused

anonymous · Answer

look at your equation and find the number where the m is in my equation.

anonymous · Answer

then flip it and take the opposite sign.

anonymous · Answer

which one is it ?

anonymous · Answer

then look for one of the equations that has that number where the m is.

anonymous · Answer

2 is the value of m in your equation.

anonymous · Answer

write 2 as a fraction by putting it over 1

anonymous · Answer

then flip it and change its sign.
