\[\boxed{\text{870\ (870).\ }\text{Еуроки\ -\ ДЗ\ без\ мороки}}\]
\[1)\ y = 2,5x + 10\]
\[2,5x + 10 = 0\]
\[2,5x = - 10\]
\[x = - 4,\ \ ( - 4;0)\]
\[Ответ:( - 4;0);\ \ (0;10).\]
\[2)\ y = 6x - 4\]
\[y = 6 \cdot 0 - 4 = - 4,\ \ (0;\ - 4)\]
\[6x - 4 = 0\]
\[6x = 4\]
\[x = \frac{2}{3},\ \ \left( \frac{2}{3};0 \right)\]
\[Ответ:(0;\ - 4),\ \left( \frac{2}{3};0 \right)\text{.\ }\]
