Пошаговое объяснение:
а) Для начала найдём цену деления координатной прямой.
(где - цена деления, - соседние числовые отметки на прямой, - кол-во делений между соседними отметками на прямой).
Значит, если расстояние между двумя соседними отметками (например, между 0 и 1) соответствует единице, то координата точки .
б) Снова находим цену деления координатной прямой.
(где - цена деления, - соседние числовые отметки на прямой, - кол-во делений между соседними отметками на прямой).
Значит, если расстояние между 2 соседними отметками (например, между 0 и 1) соответствует двойке, то координата точки .
в) Снова находим цену деления координатной прямой.
(где - цена деления, - соседние числовые отметки на прямой, - кол-во делений между соседними отметками на прямой).
Значит, если расстояние между 2 соседними отметками (например, между 0 и 1) соответствует двойке, то координата точки .
