Asked by Lydia
M is the midpoint of segment AN, A has coordinates (-6,2) and M has coordinates (-1, -3). What are the coordinates of N?
Answers
Damon
-1 - (-6) = +5
-1 + 5 = 4
-3 -2 = -5
-3 +(-5) = -8
so
(4,-8)
check
Is -1 halfway between -6 and +4
yes
Is -3 halfway between 2 and -8
yes
-1 + 5 = 4
-3 -2 = -5
-3 +(-5) = -8
so
(4,-8)

yes
Is -3 halfway between 2 and -8
yes
