Складіть рівняння прямоі яка проходить через точку D(5; -8) і паралельно на прямій y = 6x + 2

Ответы

Автор ответа: OblivionFire

Уравнение прямой имеет вид y=kx+b; у нас у=6х+2, k=6. Должно выполняться условие:

$k_{1}=k_{2}; \: b_{1} \ne b_{2}.$

Тогда, 6*5+b=-8; b+30=-8; b=-8-30; b=-38, значит ответ у=6х-38.
