-----------
Find the midpoint, that's the center.
The distance from the midpoint to either given point is the radius.
---
{{{(x-h)^2 + (y-k)^2 = r^2}}} is a circle with the center at (h,k) radius r
===================
Q2. Solve the inequality |5x+11|>7 and write the solution set in interval form.
|5x+11|>7
--------
5x+11 > 7
5x > -4
x > -4/5
==========
-(5x+11) > 7
5x+11 < -7
5x < -18
x < -18/5
