Question

The distance between the lines $8 x + 6 y = 15$ is

• A. $\frac { 7 } { 2 }$
• B. 4
• C. $\frac { 7 } { 10 }$
• D. None of these

Answer 1

Answer: (C)

$\frac { 7 } { 10 }$

Answer 2

Given lines $\frac { 11 } { 5 }$, $\frac { 15 } { 10 }$

Clearly both lines are on the same side of the origin.

Hence, distance between both the lines are, $\frac { 11 } { 5 } - \frac { 15 } { 10 } = \frac { 7 } { 10 }$.
