Questions 1) The midpoint of AB is at M(0,3). If A=(0,−2), find B.
----
No change in x, makes it simple.
Distance from M to A is 5 units.
Add 5 to M --> (0,8)
=======================
Questions 2) Write the equation of the circle centered at
C(0,−6) that passes through P(−5,−18).
----
Find the distance from C to P, that's the radius r.
r^2 = diffy^2 + diffx^2 = 12^2 + 5^2 = 169
