Question

(x-1)2 + (y + 3)2 = 73 What is the center ?

Answer 1

Answer:

centre = (1, - 3 )

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

(x - 1)² + (y + 3)² = 73 ← is in standard form

with (h, k ) = (1, - 3 ) ← centre
