    having troulbe with this on can you show how to it
    Determine which two equations represent parallel lines
    Y=3/7x+1
    Y=-7/3x-4
    Y=3x+8x
    Y=3x-1

  2. If the third equation is supposed to be
    Y = 3x + 8, rather than
    Y = 3x + 8x,
    then the last two equations have the same slope.

    For equal slopes, equations written in the form y = mx + b must have the same value of m.
