**DrBob222**, Friday, January 11, 2008 at 11:03pmy = 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.
