Distance Between a Point and a Line

To find the distance from a point $(x_0, y_0)$ to a line $ax+by+c=0$, use the formula:

Distance = $\frac{|ax_0 + by_0 + c|}{\sqrt{a^2 + b^2}}$

This involves substituting the point's coordinates into the line's equation for the numerator, and dividing by the magnitude of the normal vector of the line. Typically, the coefficients $a$ and $b$ will form a Pythagorean triple to simplify the denominator.
