Answer 1

Answer:

Its actually C his whole explanation is wrong

Step-by-step explanation:

Answer 2

D is correct.  Look at the picture of the graph I made.  The point (3,3) is in the upper right corner, not on the circle.  This is because for a circle,
x²+y²=r² where r is the radius.  If we have the point (3,0) then the equation of the circle says
$3^2+0^2=r^2 \\ r=3$

Then for r=3 we can't get the point (3,3) because
$3^2+3^2 \ \neq 3^2$
