What is the perpendicular distance of a point (2, 3) from the line 2x - 4y + 3 = 0?

What is the perpendicular distance of a point (2, 3) from the line 2x - 4y + 3 = 0?

Answer Details

2x - 4y + 3 = 0
Required distance = $\frac{(2\times 2)+3(?4)+3}{\sqrt{2^2}+(?4{)}^2}$
= $\frac{4?12+3}{\sqrt{20}}$
= $\frac{?5}{?2\sqrt{5}}$
$=\frac{\sqrt{5}}{2}$
