Question

Find the distance between (2,3) (4, -7) Find the distance between (-9,-4) (-3,6)

Answer 1

Answer:

Find the distance between (2,3) (4, -7)

= 6

Find the distance between (-9,-4) (-3,6)

= -10

Answer 2

Distance between (2 , 3) (4 , -7)

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

$d=\sqrt{(-7-3 )^{2} + (4-2 )^{2}$

$d=\sqrt{(-10 )^{2} + (2 )^{2}$

$d=\sqrt{100 + 4$

$d=\sqrt{104$

$d=10.198$ or $2\sqrt{26}$
