1.3.4 Coordinate geometry in the (x, y) plane

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

A

For A(x1,y1)A(x_1,y_1)A(x1​,y1​) and B(x2,y2)B(x_2,y_2)B(x2​,y2​), the distance is (x2−x1)2+(y2−y1)2\boxed{\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}}(x2​−x1​)2+(y2​−y1​)2​​.

B

They intersect at two distinct points.

C

It bisects the chord.

D

They touch externally, since 10=4+610=4+610=4+6.
