For this case we have that by definition, a linear function is of the form

The start of the American Revolution began because:
Americans wanted independence but, the British didn't let them have it so they had a fight. America won and then the people wrote the declaration of independence. And The American Revolution started mainly because of these reasons:
1) The colonists were being taxed, but they had no representation in Parliament. They could no agree or disagree to any laws, they had no say on HOW to tax the colonists, and more. It was a very... frustrating thing.
2) British troops were being quartered at the colonists' homes. Imagine if you were doing your daily job in the morning, and suddenly and unknown soldier bursts into your house claiming that he was quartered here and you had to provide him with a room, food, and clothing.
3) England wanted strict control over colonial legislatures. That means that if England did this, than the colonies would have no say, what-so-ever in what laws are being made for their OWN country.
4) Some colonists resented the power of colonial governors. A governor was placed in every colony. The colonists thought that the governor perhaps had TOO much power.
5) The Proclamation of 1763 hampered the western movement of settlers. This proclamation banned all settlers the freedom to move west. Things were getting crowded at the colonies and they had no choice but to move west. But this document prevented that.
That is how it was started
