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

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. 
so it would be a and d

yes
