Ling P(a,b) = (2, 3) menyinggungu sumbu y
r = jarak |a| = 2
Ling ( x- a)² - (y- b)² = r²
( x- 2)² -(y - 3)² = 4 dicerminkan terhadap sumbu x
*
Jika (x,y) --- R sbx --> (x, - y)
( x- 2)² -(y - 3)² = 4 --- R sb x --> bayangannya
x = x
y = - y
(x - 2)² + ( - y - 3)² = 4
x² - 4x + 4 + y² + 6x + 9 - 4= 0
x² + y² - 4x + 6x + 9= 0
