I need algebra help? not understanding midpoint?

Question

Answer 1

Average the x coordinates of the two endpoints.  You get 1.5.

Average the y coordinates of the two endpoints.  You get 1.5.

The midpoint of the line segment is (1.5, 1.5).

Answer 2

The Y Length 4-(-1) =5  1/2 of 5 is 2-1/2 Length.  Add this to -1 +(2-1/2) Y =1-1/2

The X length is 4-(-1)= 5  1/2 of 5 is 2-1/2 length.  Add this to -1 +2-1/2 = 1-1/2

therefore the midpoint of the line will be at coordinate (1-1/2, 1-1/2).

the midpoint (middle point) is the middle of the blue line segment, which is at 1/2 the length of the line.  It must be expressed as an (x,y) coordinate.
