Find all the points having an x-coordinate of 9 whose distance from the point (3, -2) is 10.

Question

(9, 6), (9, -10)
(9, 13), (9, -7)
(9, -12), (9, 8)
(9, 2), (9, -4)

Answer 1

So ll the points whose distance from the point (3, -2) is 10 would be the circle

(x-3)^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
