1. Use the point-slope form,
y-%28-1%29=%28%285-%28-1%29%29%2F%28-4-3%29%29%28x-3%29
y%2B1=%286%2F%28-7%29%29%28x-3%29
Convert to slope-intercept form.

2. Use the point-slope form,
y-3=%28%283-3%29%2F%280-%28-2%29%29%29%28x%2B2%29
Convert to slope-intercept form.

3. x%5E2-4x%2By%5E2%2B6y%2B12=0
%28x%5E2-4x%2B4%29%2B%28y%5E2%2B6y%2B9%29%2B12=4%2B12
%28x-2%29%5E2%2B%28y%2B3%29%5E2=4
(2,-3) and R=2.

4. %28x-5%29%5E2%2B%28y-6%29%5E2=18
