(4,3)

Explanation:

The midpoint of 2 points (x_1,y_1)" and " (x_2,y_2) is the color(blue)"average" of the x and y coordinates.

"That is " color(red)(bar(ul(|color(white)(2/2)color(black)([1/2(x_1+x_2),1/2(y_1+y_2)])color(white)(2/2)|)))

"here " (x_1,y_1)=(2,7)" and " (x_2,y_2)=(6,-1)

"midpoint " =[1/2(2+6),1/2(7-1)]=(4,3)
