Like say that decreasing the minimum wage reduces the price floor in the market. Show in a diagram that a lower minimum wage results in an increase in the quantity of labour demanded and a decrease in the quantity of labour supplied, then highlight how the top triangle (unemployment) is now smaller, etc.
But then put a sentence or two evaluating it by saying theoretically this could increase employment as I've shown on the diagram, however in reality governments face political constraints that may make reducing the minimum wage difficult in practice. For example, the UK government has never reduced the minimum wage in nominal terms despite the potential increase in employment that could result from this action. It's also not very equitable is it and is very regressive which is why you never see it in practice.
