You have $b=2-3a$. When $x=0$, given $y=ax+b$, you must have $y=b$, so $(0,2-3a)$ is on the curve. When $y=0$, it means $ax+b=0$, so $ax+2-3a$ = 0, so $x=3-\dfrac{2}{a}$.

While this is not proof, this is I think the most intuitive answer.

comment How is $e^x$ read aloud?
In French we would only say “Exponentielle de x” or “e exposant x”. When it is all about natural numbers we also use the form “10 puissance 9”.

comment What is the chance to get a parking ticket in half an hour if the chance to get a ticket is 80% in 1 hour?
As a Frenchman, 80% chance in 1 hour seems really high to me, would be rather 20% chance in 1 day.
