Question

Use the image to answer the question.

A circle is plotted on a coordinate plane.

In the circle shown, which of the following equations correctly represents the circle in standard form? Enter the option number of your response.

Option #1: (x−3)2+(y−4)2=4

Option #2: (x−4)2+(y−3)2=16

Option #3: (x−0)2+(y−3)2=16

(1 point)
Option #

Answer 1

I can’t see the image you mentioned. Please either upload the picture or tell me the circle’s center and one point on the circle (or the x- or y-intercept of the circle).

How to decide yourself:
- Standard form is (x−h)²+(y−k)²=r² where (h,k) is the center and r is the radius.
- Find the center by reading the graph’s tick marks. Then count the distance from the center to any point on the circle to get r (square that for r²).
- Compare (h,k) and r² to the three options.

If you give the center and one point (or the radius), I’ll pick the correct option.
