Question

What is the distance between point A(-2,-1) and point B (3,2)?

Answer 1

Answer:

√34

Step-by-step explanation:

A(-2 , -1)   B(3 , 2)

$Distance = \sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}\\\\ =\sqrt{(3-[-2])^{2}+(2-[-1])^{2}} \\\\=\sqrt{(3+2)^{2}+(2+1)^{2}}\\\\=\sqrt{5^{2}+3^{2}}\\\\=\sqrt{25+9}\\\\=\sqrt{34}$

$d = \sqrt{ ({2 - ( - 1)})^{2} + ({3 - ( - 2)})^{2} }$

$d = \sqrt{ {3}^{2} + {5}^{2} }$

$d = \sqrt{9 + 25}$

$d = \sqrt{34}$
