Question

Points A(-1 y) and B(5 7) lies on a circle with centre 0(2 -3y) Find y​

Answer 1

pls follow me and Mark me as branliest pls

And give me thanks

Given (7,−9)d(11,3) and center (0,0) calculating distance between the center (0,0) and (7,−9) using distance formula,

D=

(0−7)

2

+(0+9)

=

49+81

=

130

Circles equation is (x−0)

2

+(y−0)

=

130

x

+y

Now putting p+(11,3) in the above eq

n

121+9=(

130

)

130=130

Since the equation is true, that point is also on the circle.

∴ both the points lies on a circle with center at the origin.

Also, the equation is
