When you shift an equation down, you want every point to be lower than it would be. So, when you want to shift an equation down by 4, you just subtract 4 from the equation. You want y - 4. that's 4 below where y usually is. Since you're in algebra, you need should know that you have to subtract, add, multiply or divide both sides by the same amount. y = -4x-3 turns into y-4 = -4x-3-4. This simplifies to y-4 = -4x-7. y-4 is just how I'm writing y shifted down 4. Since this is a new equation that your teacher wants, you don't have to say 4 below the other one (or y-4) you can just say y, like you would in a different equation, giving you: y= -4x-7.
