To graph the equation (x^2 + y^2 - 1 = 0):

- Recognize that this equation represents a circle with a radius of 1 unit and a center at the origin (0, 0).
- Plot the center of the circle at the point (0, 0).
- Use the radius of 1 unit to plot additional points on the circle. You can use points such as (1, 0), (-1, 0), (0, 1), and (0, -1).
- Connect these points to form the circle.

The graph of (x^2 + y^2 - 1 = 0) will be a circle with a radius of 1 unit centered at the origin.
