Ответ:

1) - Б

2) - Г

3) - А

4) - В

Объяснение:

y=kx+b - прямая (её график изображен схематически)

Коэффициент b - ордината точки пересечения графика с осью Оу

Если b>0, то эта точка расположена выше оси Ох (Б и Г)

Если b<0, то эта точка расположена ниже оси Ох (А и В)

Коэффициент k - это угловой коэффициент прямой. Если k>0, то угол наклона прямой к оси Ох острый (А и Б), если k<0, то угол наклона прямой к оси Ох - тупой (В и Г).
