Graph 34=(x-4)^2+(y+7)^2
Step 1
Since is on the right side of the equation, switch the sides so it is on the left side of the equation.
Step 2
This is the form of a circle. Use this form to determine the center and radius of the circle.
Step 3
Match the values in this circle to those of the standard form. The variable represents the radius of the circle, represents the x-offset from the origin, and represents the y-offset from origin.
Step 4
The center of the circle is found at .
Center:
Step 5
These values represent the important values for graphing and analyzing a circle.
Center:
Radius:
