Answer 1

Для решения системы уравнений графическим методом, мы должны нарисовать графики обоих уравнений и найти точку их пересечения, которая будет решением системы. Давайте начнем с решения первой системы уравнений:

1. Уравнение: y - 3x = 5

Преобразуем его в форму y = mx + b:

y = 3x + 5

Теперь нарисуем график этой прямой. Выразим y как функцию от x и найдем несколько точек:

• Когда x = 0, y = 3 * 0 + 5 = 5. Имеем точку (0, 5).
• Когда x = 1, y = 3 * 1 + 5 = 8. Имеем точку (1, 8).

Теперь проведем прямую через эти две точки:

График первого уравнения:

| 8 | * (1, 8) | | 5 | * (0, 5) | +--------------------- 0 1 2 3 4 5 6

2. Уравнение: у + 2x = 0

Преобразуем его в форму y = mx + b:

y = -2x

Теперь нарисуем график этой прямой. Выразим y как функцию от x и найдем несколько точек:

• Когда x = 0, y = -2 * 0 = 0. Имеем точку (0, 0).
• Когда x = 1, y = -2 * 1 = -2. Имеем точку (1, -2).

Теперь проведем прямую через эти две точки:

График второго уравнения:

| 0 | * (0, 0) | | | * (1, -2) | +--------------------- 0 1 2 3 4 5 6

Теперь у нас есть два графика. Точка их пересечения будет решением системы. Из графика видно, что они пересекаются в точке (1, -2).

Таким образом, решение системы уравнений {y - 3x = 5; у + 2x = 0} графическим методом - это (1, -2).
