Answer 1

thts a different question

Answer 2

okay so x1=-4 y1=9 x2=8 y2=-7
(x - A)² + (y - B)² = C
A=2 B=1 C=100
x = A + r cos(α), y = B + r sin(α)
A=2 B=1 r=10
x² + y² + Dx + Ey + F = 0
D=-4 E=-2 F=-95
x-coordinate=2 y-coordinate=1
Radius=10
Diameter=20
Area =314
Circumference=62.8
ANSWER:::::::::)Standard: (x - 2)² + (y - 1)² = 10²
