Answer:
C
Step-by-step explanation:
The coordinates of A(- 2, 1 )
3 units right → + 3
2 units down → - 2
Add 3 units to the x-coordinate of A and subtract 2 from the y- coordinate
A' = (- 2 + 3, 1 - 2 ) = (1, - 1 ) → C
Answer :
<span>Unless we have a relationship defined between x and y there is no common factor apart from 1.

Answer:
(x + 3)² + (y - 7)² = 81
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 the radius
here (h, k ) = (- 3, 7 ) and r = 9 , then
(x - (- 3) )² + (y - 7)² = 9² , that is
(x + 3)² + (y - 7)² = 81
