#M(2;3,5)#

let M the midpoint
#x_M=(-4+8)/2=2#
#y_M=(2+5)/2=7/2#
so
#M(2;7/2)#
#M(2;3,5)#

#= (2 , 3 1/2)#

Find the average of the x-values and the average of the y-values.

As a formula this is, #((x_1 + x_2)/2 , (y_1 + y_2)/2)#

This gives the midpoint #(x , y)# as #((-4 + 8)/2 , (2 + 5)/2)#

#= (2 , 3 1/2)#
