Determine which lines, if any, are parrell or perpindicular
linea= y=4x
line B= y=1/4x
line c= y= 4x1
I think line B and A are parrell.
Am I correct?
Please help me, thank you.

Algebra one help, please. 
Person_blah,
I'll help.
Lines a and c are parallel. For lines to be parallel, their slope must be equal. These 2 lines both have slopes of 4. Line b is perpendicular to the others, because it's slope, 1/4, is the opposite (in terms of sign) reciprocal of 4 (which is positive, 1/4 is negative). I hope this helped. Peace out.
