Point M is the midpoint of . Can the value of variable a be​ determined? Explain. x y graph
Select the correct choice below​ and, if​ necessary, fill in the answer box to complete your choice.
A.
To determine the value of​ a, divide each coordinate of M by 2. Then add each quotient to the​ x- and​ y-coordinates of M. The value of a is
nothing.
B.
To determine the value of​ a, set the​ x- and​ y-coordinates of G and F equal to each other and solve for a. The value of a is
nothing.
C.
To determine the value of​ a, set up and solve a system of equations in two variables. The value of a is
nothing.
D.
Not enough information is given for the value of a to be determined. Point M is the midpoint of . Can the value of variable a be​ determined? Explain.
