determine weather each pair of equations represents perpendicular lines. show work
y= -x+7
y -x =3

Question

anonymous · Answer

those arent perpendicular lines, those are parallel because they have the same slope.

myininaya · Answer

right them both in y=mx+b form

anonymous · Answer

oops sorry i looked at the equations wrong ><

myininaya · Answer

y=-x+7
y=x+3
sp they are perpendicular since the slope of the first line is 1 and slope of the second line is -1 and their product is -1

anonymous · Answer

perpendicular lines have to have reciprocal slope. for example, 
y = 2x+2
y = -1/2x+5 
those two are perpendicular lines because theyre negative reciprocals of eachother. see what i mean?

yes i do see..thank u both
