I can't figure this out at all

Determine which two equations represent parallel lines. y=-4x+1,y=4x+1,y=1/4x+1,y=-4x+5

  • math -

    y = mx + b is the general equation for a straight line. To be parallel, you want the lines to have the same slope; therefore, m in the general equation should be the same. If your equation is
    y = -4x + 1, you want the parallel line to be -4x + anything. Check my thinking.

  • math -

    so it would be a and d

  • math -

    yes
