Given points A(9, 3), B(–3, 6), and C(–7, –3). Which statements describe the vectors that include these points? Check all that apply. The magnitude of Vector A C is StartRoot 2 EndRoot. The magnitude of Vector B C is StartRoot 97 EndRoot. The magnitude of Vector A B is 3 StartRoot 17 EndRoot. Vector A C = LeftAngleBracket negative 16, negative 6 RightAngleBracket Vector B C = LeftAngleBracket 10, 9 RightAngleBracket Vector A B = LeftAngleBracket negative 12, 3 RightAngleBracket

-2x+8=y=x-1
-2x+8=x-1
add 2x to both sides
8=3x-1
add 1
9=3x
divide 3
3=x
sub
y=x-1
y=3-1
y=2

(x,y)
(3,2)
