Question

Find the distance between (4,2) and (-4,-4)

Answer 1

Use the distance formula, and plug in values.
$d = \sqrt{(x_{2}-x_{1} )^{2}+(y_{2}-y_{1} )^{2}}$
<u />$d = \sqrt{( -4-4 )^{2}+( -4-2 )^{2}}$
$d = \sqrt{( -8 )^{2}+( -6 )^{2}}$
$d = \sqrt{64+36}$
$d= \sqrt{100}$

Therefore, the distance is equal to "10".
