Автор ответа: АнгелНаЗемле

Линейная функция - это функция, которую можно задать формулой y= kx+b, где x - независимая переменная, k и b- некоторые числа. Число k - угловой коэффициент прямой, т.е. графика функции y=kx+b. Если k>0, то угол наклона прямой у оси x острый. Если k<0, то угол тупой. Если угловые коэффициенты прямых различны, то эти прямые пересекаются. А если угловые коэффициенты одинаковы, то прямые параллельны.
Графиком линейной функции является прямая. Если y=kx, то прямая проходит через начало координат (0;0). Если y=kx+b, то прямая смещена на b единиц.

There are more than 60 universities in Britain. But not all universities are equal. They differ from one an other in history, tradition, academic organisation. Not all British universities have a well-known reputation. Oxford and Cambridge, the oldest universities, are world known for their academic excellence. The University of London has the size and breadth to rank among the UK' stop universities. A university usually consists of colleges. The departments of the colleges are organised in to faculties. University teaching in the UK differs greatly at both undergraduate and postgraduate levels from that in many other countries. An undergraduate programme consists of a series of lectures, seminars, tutorials and laboratory classes which in total account for about 15 hours per week. Following a particular programme students take series of lecture courses which may last one academic term or the whole year. Associated with each lecture course are seminars, tutorials, laboratory classes which illustrate the topics presented in the lectures.
Lectures are given to large groups of students (from 20 to 200). Seminars and tutorials are much smaller than lecture classes and in some departments can be on a onetoone basis (one member of staff and one student).Students prepare work in advance for seminars and tutorials. And this can take the form of a topic for discussion by writing essays or by solving problems. Lectures, seminars and tutorials are all one hour in length, laboratory classes last two or three hours. Each student has a tutor whom he can consult on any matter whether academic or personal.
The academic year is split into three terms. Formal teaching takes place in the first two terms which last for twenty four weeks in total. The third term is reserved for classes and examinations and lasts for six weeks. Universities teach in all major subject areas: arts, science, law, engineering, medicine, social sciences. University staff are chosen for the best knowledge in their subject. The teaching encourages students to learn in the most effective way. University degree courses extend from three to four years. After three years of-study at the University graduates will leave with the Degree of Bachelor of Arts or Science. They can continue to take their Master's Degree and then the Doctor's Degree.
