Answer

The standard form of the equation of the circle is \((x + 4)^2 + (y + 3)^2 = 25\).

Solution

It seems that I am unable to generate a graph at the moment. However, I can guide you on how to graph the circle manually. ### Steps to Graph the Circle 1. **Draw the Coordinate Axes:** - Draw a horizontal line for the x-axis and a vertical line for the y-axis. 2. **Plot the Center:** - Mark the center of the circle at the point \((-4, -3)\). 3. **Mark the Radius:** - From the center, measure \(5\) units in all four cardinal directions: - Right to \((1, -3)\) - Left to \((-9, -3)\) - Up to \((-4, 2)\) - Down to \((-4, -8)\) 4. **Draw the Circle:** - Using a compass or freehand, draw a smooth curve connecting these points to form the circle. ### Final Note You now have both the standard and general forms of the equation of the circle, and you can graph it using the steps provided. If you have any further questions or need additional assistance, feel free to ask!

The standard form of the equation of a circle with radius \( r \) and center \( (h, k) \) is given by the formula: \[ (x - h)^2 + (y - k)^2 = r^2 \] For your circle, substituting \( r = 5 \) and \( (h, k) = (-4, -3) \) gives: \[ (x + 4)^2 + (y + 3)^2 = 25 \] The general form of the equation can be obtained by expanding the standard form. Expanding \( (x + 4)^2 + (y + 3)^2 = 25 \) results in: \[ x^2 + 8x + 16 + y^2 + 6y + 9 = 25 \] Simplifying this gives: \[ x^2 + y^2 + 8x + 6y = 0 \] Now, when you graph this circle, you'll place the center at the point (-4, -3) and draw a circle that extends 5 units in all directions from that center, creating a lovely round shape on the coordinate plane!
