Point T , the midpoint of segment line segment R S , can be found using the formulas x is equal to 1 half times open paren 6 minus 2 close paren plus 2 and y is equal to 1 half times open paren 4 minus 6 close paren plus 6 What are the coordinates of point T ?
Answer
A
T 3 comma 2
B
T 4 comma 7
C
T 3 comma 4
D
T 4 comma 5
Explanation
Evaluate each coordinate formula. For x, one-half of (6 − 2) plus 2 is 2 + 2 = 4. For y, one-half of (4 − 6) plus 6 is −1 + 6 = 5, so point T has coordinates (4, 5), choice D.
