Are the lines 12x plus 3y-9 and -8x-2y14 parallel?

If you mean 12x+3y = -9 and -8x-2y = 14 then they are y = -4x-3 and y = -4x-7 respectively which means that they are parallel lines because they both have the same slope of -4 but with different y intercepts

Is this equation 9x plus 3y equals 12 and 12x plus 4y equals 18 parallel?

Yes the equation is parallel and this is why.... when you put the formula 9x+3y=12 in a slope intercept form you'll get 9x+3y=12 9x+3y-12=0 3y= -9x+12 divide by 3 y=-3x+4 12x+4y=18 12x+4y-18=0 4y= -12x+18 divide by 4 y= -3x + 9/2 In order for two equations to be parallel the slope must be equal to each other remember the slop is the m in y=mx+b. Since both equations have -3 as it's slope that makes them parallel lines.

What is the equation of a line that is parallel to 3y equals -12x plus 9 and that has a y-intercept of -4?

y = - 4x - 4
