    wait but aren't those the points of the vertices I think B. is probably the point of the co-vertices

    Well the coordinates of B are just the two points that show the middle of the top and bottom line

    Do you know what the foci of that graph would be? These are the options: (1, -2) and (3, 4) (-5, -2) and (7, -2) (-6, -2) and (8, -2) (-4, -2) and (6, -2)

    this would be a guess, I'd say D

    just did a rough graphical calculation and this confirms my previous answer D
