Question

If a line segment has endpoints A(3x + 5, 3y) and B(x − 1, −y), what are the coordinates of the midpoint of AB ?
(1 point)
(x + 3, 2y)
(2x + 3, y)
(2x + 2, y)
(4x + 4, 2y)

Answer 1

Add the x values and divide by 2 then add the y values and divide by 2

Answer 2

(3x+5+x-1)/2=(4x+4)/2=2x+2
(3y+-y)/2=(2y)/2=y

Answer 3

is the answer (2x+2,y)
