Final answer:
The coordinates of point L, the midpoint of JK, are calculated as (3, -2) by adding and subtracting the values inside the parentheses of the given equation M.
Step-by-step explanation:
The coordinates of point L, the midpoint of JK, are given by the equation M = (5+1/2 , 3-7/2). To find these coordinates, we simply need to perform the arithmetic operations within the parentheses. Adding 1 to 5 and dividing it by 2 gives us 3 divided for the x-coordinate, and subtracting 7 from 3 and dividing it by 2 gives us -2 for the y-coordinate. Therefore, the coordinates of point L are (3, -2).
