Question

Distance between the two parallel lines $y equals 2 x plus 7$ and $y equals 2 x plus 5$ is

$\frac{\sqrt{5}}{2}$
$\frac{2}{5}$
$\frac{2}{\sqrt{5}}$
$\frac{1}{\sqrt{5}}$

The correct answer is: $fraction numerator 2 over denominator square root of 5 end fraction$

Given lines are $2 x minus y plus 7 equals 0$ and $A B equals 2 A D equals 2 square root of 81 minus 9 end root equals 2 square root of 72 equals 12 square root of 2$
Both the lines are on same side of origin.
Distnace between two parallel lines = $fraction numerator 7 minus 5 over denominator square root of 2 to the power of 2 end exponent plus 1 to the power of 2 end exponent end root end fraction equals fraction numerator 2 over denominator square root of 5 end fraction$ .
