  hello : an equation of the circle Center at the A(a,b) and ridus : r is : (x-a)² +(y-b)² = r² in this exercice : a = -2 and b = 1 (Center at the A(-2,1)) r = AP......P( -4 , 1) r² = (AP)² r² = (4+2)² +(1-1)² = 36 an equation of the circle that satisfies the stated conditions. Center at  A(-2,1), passing through P(-4, 1) is : (x+2)² +(y-1)² = 36
