Indicate the equation of the line that is the perpendicular bisector of the segment with endpoints (4, 1) and (2, -5). fill in the blank i have no idea how i'd solve this, also some pointers would be nice for future references if you don't mind. : )

What are the sotions to the quadratic equation 9x^2=4

Ineed in figuring out this problem.

On traditional maps, earth is represented in a flat plane, or by euclidean geometry. however, a globe is a more accurate model that comes from elliptical geometry.how does a globe represent the fact that there are no parallel lines in elliptical geometry? the equator is not parallel to any other latitudinal lines. the north and south poles are never connected by a geodesic. the geodesics connecting the north and south poles never intersect. the geodesics connecting the north and south poles intersect at both of the poles.
