1.2.6 Co-ordinate geometry in the x, y plane

A circle has radius 555. What is its diameter?

A

The half-length is 444, so the chord is 888.

B

The diameter is 101010.

C

For two non-vertical perpendicular lines, m1m2=−1\boxed{m_1m_2=-1}m1​m2​=−1​.

D

52−32=\strong4\sqrt{5^2-3^2}=\strong{4}52−32​=\strong4.
