To find the coordinates of point L , the midpoint of line segment J K , the equation M is equal to the fraction with numerator 5 plus 1 and denominator 2 comma the fraction with numerator 3 minus 7 and denominator 2 can be used. What are the coordinates of point L ?
Answer
A
L 1 comma negative 7
B
L 3 comma negative 2
C
L 5 comma 3
D
L 6 comma negative 4
Explanation
Use the midpoint formula by calculating each coordinate separately: (5 + 1) ÷ 2 = 3, and (3 − 7) ÷ 2 = −2. Therefore, point L has coordinates (3, −2), which is choice B.
