Question

Solution

Correct option is

3.5

Note that, two lines are parallel as their slopes are equal.

Distance between two parallel lines Ax + By + C1 = 0 and

Ax + By + C2 = 0 is given by: To use this result, write the given equations as:

6x + 8y – 45 = 0                     …. (i)

and            6x + 8y – 10 = 0                    … (ii)

i.e. making the coefficient of xy same in respective equations
