To find the coordinates of point L, the midpoint of JK, the equation M = can be used. What are the coordinates of point L? L(1,

anygoal [31]

Since we are already given with the formula to solve for the coordinates of point L, all we have to do is to perform the necessary operation in the item. The formula for the coordinates of the midpoint is, M = ((5 + 1) / 2 , (3 - 7) / 2)performing the operation, M = (3, -2)Thus, the coordinates of point L are (3,-2).
