Question

Find the distance between two points A(-1,3) and B(4,5)​

Answer 1

Use distance formula :  $\sqrt{\left(x_{2}-x_{1}\right)^{2}+\left(y_{2}-y_{1}\right)^{2}}$

$\begin{array}{l}\sqrt{\left(x_{2}-x_{1}\right)^{2}+\left(y_{2}-y_{1}\right)^{2}} \\\\=\sqrt{(4-(-1))^{2}+(5-3)^{2}} \\\\=\sqrt{(4+1)^{2}+(2)^{2}} \\\\=\sqrt{(5)^{2}+(2)^{2}} \\\\=\sqrt{25+4} \\\\=\sqrt{29}\end{array}$

Answer 2

Your answer is √29
