    how about the center is not given then the tangent line is x+y=2?????

    what if only 0ne center? and given the center of tangent?

    Did you forget to get the square root of the denominator; numerator shouldn't even be squared? Equation should be Ah + Bk + C / the square root of A squared + B squared.

      The answer should be negative square root of 13; or -3.61

      Hello…i am using r² formula so that easy to find the value… that formula you said if you’re solving for r.

      Find the equation of the circle with the center at (-4,2) and tangent line to the line 2x-y+2=0
      h= -4
      k= 2
      2x-y+2=0
      A= 2
      B= 1
      C= 2
      r² (Ah+Bk+C)² over A²+B²
      = (2(-4)+(1)(2)+2)² over 2²+1
      = (-8+2+1)² over 4+1
      = (-11)² over 5
      = 125 over 5 => r² = 24.2
      (x+4)²+(y-2)² = 24.2
