Determine whether the points ( -2,1) ,(0,0) and ( -4,-3) lie outside, on or inside the circle ` x^(2) + y^(2) - 5x + 2y - 5 =0`

Without drawing the figure determine whether the points (0,0),(-2,1),(4,-3),(2,6),(0,-1) lie outside the circle or on or inside the circle x^2+y^2-5x+2y-5=0

The point (1,2) lies inside the circle x^(2) + y^(2) - 2x + 6y + 1 = 0 .

The point (1,2) lies inside and (3,4) outside the circle x ^(2) +y ^(2) - 7x + 15 y - c =0, if

The point (1,2) lies inside the circle x^(2)+y^(2)-2x+6y+1=0 .

Does the point ( 2,5), (3,5) lie inside, outside or on the circle x^2+y^2=25 ?

Does the point (2,5),(3,5) lie inside,outside or on the circle x^(2)+y^(2)=25?

Does the point (-2,5,3.5) lie inside, outside or on the circle x^2 + y^2 = 25 ?

Show that the points (4,2) (3,-5) are conjugate points with respect to the circle x^(2) + y^(2) -3 x - 5y + 1 = 0
