The points (-1,-9) and K(5,1) are endpoints of a diameter of circle 5. Which equation represents circle 5? OB.
O A. (x - 2)2 + (y + 4)2 = 34
(x - 2)2 + (y + 4)2 = 136
C. (x + 2)2 + (y - 4)2 = 34
D. (x + 2)2 + (y - 4)2 = 136

step-by-step explanation:

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
