Ответы

Автор ответа: kristinabelous

график линейной функции: y=kx+b

подставляем под эту формулу точки (3;0) и (0;-4)

0=3k+b

-4=b (это системой)

b=-4, значит, 0=3k-4

k=4/3

теперь подставляем под формулу:

y=4/3x-4

Переведите текст:
When Americans are introduced for the first time, they usually shake hands, when they meet friends or relatives they haven't seen for a while, they sometimes kiss them on the cheek. It is common for two women or a man and a woman to kiss in that way, but men almost never kiss each other on the cheek.
America is a friendly country. In small towns people say "hello" to friends and strangers on the street, even in cities strangers may start up a conversation. Waiters in restaurants will often introduce themselves by name, and talk with the customers as they serve them. When the customers leave, they will tell them to "take care" or "have a nice day". Sometimes foreigners feel that Americans are too friendly. People you have only just met ask you personal questions or tell you all about themselves.
Many people take a bottle of wine or some flowers when they are invited to dinner at someone's home, at a "pot luck dinner, all the guests bring something to eat. You should ask your hosts what kind of food they would like you to bring. Usually it is a salad, vegetable, or a dessert. When you are invited to dinner, it is usually to arrive ten or fifteen minutes late, this gives the hosts time to finish their preparations.
Americans like to get together and to have parties. Traditional party occasions are a birthday, moving to a new house, a wedding, New Year's Eve, and the Fourth of July. "Bridal showers" are for women who are getting married, and "baby showers" are for women who have just had a baby. All the guests bring a useful present for the new home or the new baby.
In the U.S. there aren't too many rules for different social occasions. Americans like to relax and enjoy themselves, and most social occasions are informal. So maybe the best advice is to relax, smile, and enjoy yourself too!
