Perhaps you could add what you think "Regressive" means in your own words, and then try to come up what that means mathematically?

Is T a tax rate or taxes in units of Y?

@BKay Good question, I'm quite sure it's taxes in units of Y. I'm from Belgium but if I try and translate it's: "total indebted tax"

Don't you mean "*the higher the income, the lower the **marginal** tax*"?

@FooBar yes, that's what I meant. I have the feeling that I'm missing/overlooking something very easy/trivial ;)

As a first step, try drawing what the average and marginal tax rates look like. That might help.

You're correct it is graph A. Regressive tax means that the lower income you have the higher %tax you have. If you imagine at the lowest level of income, you still have a flat tax(The intercept).

Since the slope is constant the %tax component is the same for all income levels.

Therefore this flat tax component is the part you need to look at. The flat tax represents a larger proportion for lower income earners. As a whole (%tax + Flat tax) the tax is then a higher % for lower income earners, hence regressive taxation.
