Question

1.Find equation of circle tangent to both axes containing (-8,-1)
2.Same question but containing (7,2)

Answer 1

someone send a warning to this guy

Answer 2

@ryan123 you shouldn't be doing that ...

Answer 3

this is the situation. Like you can deduce from picture, circle will have center (-a,-a), radius a. Circle equation is:
\[(x-h)^{2}+(y-k)^{2} =r ^{2}\]
plug the values i gave you above and the point coordinates for x,y and solve for a and you got it

Answer 4

got it?

Answer 5

Thanks! so there are two circle that have radii of 5 and 13?

Answer 6

*circles

Answer 7

Answer 8

obviusly radius 13 is not acceptable
