Write the formula for the distance $d$ from ${P}_{1}=\left({x}_{1},{y}_{1}\right)$ to ${P}_{2}=\left({x}_{2},{y}_{2}\right)$.

The solution is $d=\sqrt{{\left({x}_{2}-{x}_{1}\right)}^{2}+{\left({y}_{2}-{y}_{1}\right)}^{2}}$.

${P}_{1}=\left({x}_{1},{y}_{1}\right)$ and ${P}_{2}=\left({x}_{2},{y}_{2}\right)$

The formula for the distance $d$ from ${P}_{1}=\left({x}_{1},{y}_{1}\right)$to ${P}_{2}=\left({x}_{2},{y}_{2}\right)$ is -

$d=\sqrt{{\left({x}_{2}-{x}_{1}\right)}^{2}+{\left({y}_{2}-{y}_{1}\right)}^{2}}$
