find the coordinate of a point A where AB is the diameter of a circle whose center is C(1 , -3 ) and B is (-2 , -5 ) |
|
Answer» x=4 and y= -1Step-by-step EXPLANATION:let coordinate of A be (x,y)AB is a straight line whose CENTRE is C so we know C(1,-3) =( coordinate of A+ coordinate of B)/2C( 1,-3) =[ {x+(-2)}/2 {y+(-5)}/2]C( 1,-3) =[ (x-2)/2 (y-5)/2]so ( x-2)/2=1 (y-5)/2= -3x-2=2 y-5= -6x=2+2 y= -6 +5 hope it helps. mark as brainliest |
