Determine which lines, if any, are parrell or perpindicular

linea= y=4x

line B= y=-1/4x

line c= y= 4x-1

I think line B and A are parrell.

Am I correct?

Please help me, thank you.

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.
