Ahiker is lost in the woods. a search team has created a coordinate grid to represent the woods. each unit on the grid is one square mile. the hiker was last seen at (4, -9) and could have walked 10 miles in any direction since then. which equation represents the area the hiker could be in? a) (x - 4)2 + (y + 9)2 = 102 b) (x + 4)2 + (y - 9)2 = 102 c) (x + 4)2 + (y + 9)2 = 1002 d) (x - 4)2 + (y - 9)2 = 1002
