Question

Line Segment GH and Point Kare shown on the coordinate plane below.What is the distance from Point K to the midpoint of to the nearest tenth of a unit?

Answer 1

We have to find the mid point first:

$(\frac{9+-5}{2},\frac{8+-2}{2})=(2,3)$

so the distance from K to the midpoint is

$d=\sqrt[]{(-1-2)^2+(-3-3)^2}=\sqrt[]{9+36}=\sqrt[]{45}\approx6.7$
