The mid-point for given endpoints is (4,3)
Step-by-step explanation:
a mid-point is the point on a line segment that divides it into two equal portions.
If (x1,y1) and (x2,y2) are the coordinates of vertices of a line segment, then mid-point is given by:

given
(x1,y1) = (9,9)
(x2,y2) = (-1,-3)

The mid-point for given endpoints is (4,3)

Answer:
(3, - 4)
Step-by-step explanation:
Under a reflection in the y- axis
a point (x, y ) → (- x, y ), hence
(- 3, 4 ) → (3, - 4 )
