No because (7,2)
(
7
,
2
)
is not the coordinate of point J or K.
No because open paren 7 comma 2 close paren is not the coordinate of point J or K.

Yes because (7+2)÷2
(
7
+
2
)
÷
2
calculates the average, or midpoint, of the x-coordinates of points J and K.
Yes because open paren 7 plus 2 close paren divided by 2 calculates the average, or midpoint, of the x -coordinates of points J and K.

Answer 1

Yes — (7+2)÷2 gives the average of the y-coordinates. (7+2)/2 = 4.5, and the midpoint is ((-6+4)/2, (7+2)/2) = (-1, 4.5).
