Question

find the distance between
the following pairs of points.
(3,2).​

Answer 1

Answer:

LetA(2,3)=(x

1

,y

1

)andB(4,1)=(x

2

,y

)

Distance = AB = \sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}Distance=AB=

(x

+(y

\begin{gathered}= \sqrt{ (4-2)^{2} + (1-3)^{2}}\\=\sqrt{2^{2} + (-2)^{2}}\\=\sqrt{ 4+4} \\=\sqrt{8}\\=\sqrt{2\times 2\times 2} = 2\sqrt{2}\end{gathered}

=

(4−2)

=

4+4

=

8
