1.2.5 Co-ordinate geometry in the x, y plane

For points A(x1,y1)A(x_1,y_1)A(x1​,y1​) and B(x2,y2)B(x_2,y_2)B(x2​,y2​), [...]\text{[...]}[...].

A

(x−2)2+(y+3)2=25(x-2)^2+(y+3)^2=25(x−2)2+(y+3)2=25

B

For points A(x1,y1)A(x_1,y_1)A(x1​,y1​) and B(x2,y2)B(x_2,y_2)B(x2​,y2​), AB2=(x2−x1)2+(y2−y1)2\boxed{AB^2=(x_2-x_1)^2+(y_2-y_1)^2}AB2=(x2​−x1​)2+(y2​−y1​)2​.

C

The centre is (−3,5)(-3,5)(−3,5).

D

(x+3)2−9(x+3)^2-9(x+3)2−9
