Use the Midpoint Formula.

(0.5,5.5)

Practice makes perfect
To find the midpoint, we can use the Midpoint Formula. M(x_1+x_2/2,y_1+y_2/2) The coordinates of the given endpoints are (2,4) and (-1,7). Let's use these to find the coordinates of the midpoint.
(x_1+x_2/2,y_1+y_2/2)
(2+( -1)/2,4+ 7/2)
(1/2,11/2)
(0.5,5.5)
The midpoint is located at (0.5, 5.5).
