उत्तर

Here, in all equations the coefficient of x is same.
It means all the lines have same slope
So, all the lines are parallel.
Now, the distance between the line 3x + 4+ 2 = 0 and 3x + 4y + 5 = 0 is given by

\[\frac{\left| 2 - 5 \right|}{\sqrt{3^2 + 4^2}}\]
\[ = \left| \frac{3}{\sqrt{25}} \right| = \frac{3}{5}\]

Again, the distance between the line 3x + 4+ 2 = 0 and 3x + 4y − 5 = 0 is given by

\[\frac{\left| 2 + 5 \right|}{\sqrt{3^2 + 4^2}}\]
\[ = \left| \frac{7}{\sqrt{25}} \right| = \frac{7}{5}\]

Hence, the ratio is given by

\[\frac{3}{5} : \frac{7}{5}\]
\[ = 3 : 7\]
