Question

A segment has endpoints at (15,-11) and (42,-11).How many units long is the segment?

Answer 1

Id say the answer is D i might be wrong tho

Answer 2

Hey there,

You have to use this formula : 

$D= \sqrt{( x_{2} - x_{1})^2 + ( y_{2} - y_{1} )^2 }$
$D= \sqrt{( 42 - 15 )^2+( -11 + 11 )^2$
$D= 27$

Therefore, the answer would be the option B.

Hope this helps !
