Question

L (5, -8) and M (-7,-3) then the distance between point ​

Answer 1

L (x1 , y1) = (5 , -8)

M (x2 , y2) = (-7 , -3)

$d = \sqrt{( {x2 - x1)}^{2} + {(y2 - y1)}^{2} } \\ d = \sqrt{ {( - 7 - 5)}^{2} + (- 3 - ( - 8 {))}^{2} } \\ d = \sqrt{( { - 12)}^{2} +( { - 3 + 8)}^{2} } \\ d = \sqrt{144 + ( {5)}^{2} } \\ d = \sqrt{144 + 25 } \\ d = \sqrt{169} \\ d = 13 \: units$
