Question

Reduce the equation into normal form. Find their perpendicular distance from the origin and angle between perpendicular and the positive x-axis.
$y-2=0$

Answer 1

Solution -

$y-2=0$

$\frac{y}{2}=1$ --Normal Form

Distance from oigin $=\left|\frac{-2}{\sqrt{1}}\right|=2$

Angle with positive x-axis $=ta{n}^{-1}\left(0\right)={\theta }^{\circ }$

Angle with $\perp$ positive x-axis $={90}^{\circ }-0^{\circ }={90}^{\circ }$
