1: vecto AC=(-1;-7)

=>VTPT là (-7;1)

PTTS là:

x=3-t và y=6-7t

Phương trình AC là:

-7(x-3)+1(y-6)=0

=>-7x+21+y-6=0

=>-7x+y+15=0

2: Tọa độ M là:

x=(3+2)/2=2,5 và y=(6-1)/2=2,5

PTTQ đường trung trực của AC là:

-7(x-2,5)+1(y-2,5)=0

=>-7x+17,5+y-2,5=0

=>-7x+y+15=0

3: \(AB=\sqrt{\left(-1-3\right)^2+\left(3-6\right)^2}=5\)

Phương trình (A) là:

(x-3)^2+(y-6)^2=AB^2=25
