Answer:
T ( 9, 4 )
Explanation:
A really simple way to find any end-point or mid-point is to take your given points and see how far they are from each other. Since M is the mid-point and U is one of the end-points, you can look at them and see x is going up by 3 and y is going up by 2. This would make T ( 9, 4 ).
( 9, 4 ) T
^ ^
+3 +2
( 6, 2 ) M
^ ^
+3 +2
( 3, 0 ) U
Hopefully this isn't too confusing I tried my best to explain. Have a good dayyy!
