Mis the midpoint of AN, A has coordinates (-5,-5) and M has coordinates (3, 4) Find the coordinates of N.
1 answer:
Answer:
N(11 , 13)
Step-by-step explanation:
M(3,4) = (x,y)
A(-5, -5) = (x1,y1)
N ( )=(x2,y2)
using midpoint formula;
M(x,y)=(x1 + x2)/2 , (y1 + y2)/2
(3,4)= (-5 + x2)/2 , (-5 + y2)/2
Now;
3 = (-5+x2)/2 4 = (-5 +y2)/2
6 = -5 +x2 8 = -5 +y2
6+5 = x2 8+5=y2
x2=11 y2 = 13
