Circles
Practice
1. Graph the circle with the equation:
$$(x + 4)^2 + (y + 2)^2 = 25$$
$$(2, 7)$$
$$(-2, 3)$$
$$(6, 3)$$
$$(2, -1)$$
2. What is the equation of the circle above?
3. a) Draw a circle in Quadrant IV, with
1 y intercept and no x intercepts.
b) Give the equation of your circle.
Hint: you can redraw your circle to make the radius
or center point nicer.
