Answer 2

Answer:

l (PM): y = -2/3x + 2

y-coordinate: -1

Step-by-step explanation:

B (x, y): (x+1)/2 = 3      x = 5

            (y + -2) / 2 = 1     y = 4 ... B (5,4)

slope of AB = (4- -2)/(5-1) = 3/2

PM bisect AB, PM⊥ AB

slope of AB =  - 2/3

equation of PM : (y-1)/(x-3) = -2/3

y-1=-2/3x+2

y = -2/3x+3

PA = PB = radius    P (6,k)

PA² = PB² ... (6-1)²+(k- -2)² = (6-5)²+(k-4)²

25+k²+4k+4 = 1+k²-8k+16   ... -K² both side

12k = -12        k = -1

P (6 , -1)   r = √(6-1)²+(k- -2)² = √(6-1)²+(-1- -2)² = √26

equation of circle: (x-h)² + (y-k)² = r²  .. h=6, k=-1, r=√26

I'm sure you can figure out the equation by yourself... :)
