The circle passing through ( 1 , - 2 ) and touching the axis of x at ( 3 , 0 ) also passes through the point

The circle passing through (1,-2) and touching the axis of x at (3,0) also passes through the point
  1. 5,-2
  2. -2, 5
  3. -5, 2
  4. 2, -5

Solution



Alt : Equation of circle

(x−3) 2 + (y+r) 2 = r 2

Passes through 1, -2

∴ r=2

∴ Circle (x−3) 2 + (y+2) 2 =4

Passes through (5,-2).
