Question

Ryan’s teacher asked him to graph circle E with equation (x – 5)2 + (y – 1)2 = 25. Below is the graph he submitted.
What, if anything, did Ryan do wrong when graphing this equation?

He graphed a circle with center at (-5, -1) instead of at (25, 1).

He graphed a circle with center at (-5, -1) instead of at (5, 1).

Ryan’s graph is accurate.

He graphed a circle with a radius of 5 instead of a radius of 25.

Answer 1

hint: the general equation of a circle is

(x - a)^2 + (y - b)^2 = r^2

where (a, b) is the centre and r = 5.

Answer 2

so x=25,y=1,r=625?

Answer 3

i mean r=5?

Answer 4

am i correct?

Answer 5

is the answer his graph is accurate?

Answer 6

no r radius is 5 as you said but the centre (a,b ) is (x coordinate, y coordinate) = (5 , 1)
0

Answer 7

B?

Answer 8

ignore that 0 at the end....

Answer 9

right

Answer 10

thanks
