Correct Answer - Option 2 : 5/13

Concept:

The distance between two parallel lines ax + by + c1 = 0 and ax + by + c2 = 0 is given by the formula: \(\rm d=\dfrac{|c_1-c_2|}{\sqrt{a^2+b^2}}\).

Calculation:

Using the concept above, we have a = 5, b = -12, c1 = 2 and c2 = -3.

∴ \(\rm d=\dfrac{|c_1-c_2|}{\sqrt{a^2+b^2}}\)

\(\rm \dfrac{|2-(-3)|}{\sqrt{5^2+(-12)^2}}\)

\(\rm \dfrac{|5|}{\sqrt{169}}\)

\(\dfrac{5}{13}\).
