\[\boxed{\mathbf{73}.}\]
\[1)\ y = - 5x + 8\]
\[y = 0:\]
\[- 5x + 8 = 0\]
\[- 5x = - 8\]
\[x = 1,6.\]
\[x = 0:\]
\[y = - 5 \cdot 0 + 8 = 8.\]
\[Ответ:(1,6;0);(0;8).\]
\[2)\ y = \frac{1}{4}x - 3\]
\[y = 0:\]
\[\frac{1}{4}x - 3 = 0\]
\[\frac{1}{4}x = 3\]
\[x = 12.\]
\[x = 0:\]
\[y = \frac{1}{4} \cdot 0 - 3 = - 3.\]
\[Ответ:(12;0);\ \ (0;\ - 3).\]
