To graph a circle in the Lines and Conics App, follow the steps below:

Example:

Graph the circle in standard form (x-6)^2+(y-7)^2=3^2

1.    Select the Lines and Conics App icon  from the Home Screen.

2.    Press = in an empty equation to add an equation template.

3.    Select the template by using the left arrow key ‹ and right arrow key › to change the templates.

4.    Fill in the equation template using the numbers and arrow keys to navigate the entries.

NOTE: use the plus + and minus − signs to change the signs within the template.

5.    Press = to complete the entry.

6.    Press h to view the graph.

Note: Points of Interest Trace will find points of interest on equations that are functions (lines and vertical parabolas) if it is turned on. Press [trace] to explore the graph.

Note: Toggle between Y= editor and E: editor entry to manage the graphs of functions by pressing the c key.
