Find all the points having an xcoordinate of 9 whose distance from the point (3, 2) is 10.
(9, 6), (9, 10)
(9, 13), (9, 7)
(9, 12), (9, 8)
(9, 2), (9, 4)

math 
Reiny,
So ll the points whose distance from the point (3, 2) is 10 would be the circle
(x3)^2 + (y+2)^2 = 100
when x = 9
36 + (y+2)^2 = 100
(y+2)^2 = 64
y + 2 = ± 8
y = 6 or y = 10
looks like choice #1
