6. TRY IT

Determine the posisition of points (4,-5),

(3,7), (8,9) and (2,1) with respect to a circle

having an equation of X2 + Y2 = 58.

HOME WORK Given the equation of a circle

X2 + Y2 – 4x – 6y – 12=0 a.) Determine the power value of

points A(1,2), B(6,6), and C(8,2).b.) Then determine the position of

points A, B, and C with respect to the circle.
