The correct Answer is:
To solve the given statements, we will analyze each statement step by step. ### Statement 1: The equation \( x^2 - y^2 - 4x - 4y = 0 \) represents a circle with center (2, 2) passing through the origin. **Step 1: Rearranging the equation** We start with the equation: \[ x^2 - y^2 - 4x - 4y = 0 \] Rearranging gives: \[ x^2 - 4x - y^2 - 4y = 0 \] **Step 2: Identifying the form of the equation** The general equation of a circle is: \[ (x - h)^2 + (y - k)^2 = r^2 \] where \((h, k)\) is the center and \(r\) is the radius. However, our equation has a minus sign between the \(x^2\) and \(y^2\) terms, indicating that it is not in the form of a circle. **Step 3: Conclusion for Statement 1** Since the equation has a minus sign between \(x^2\) and \(y^2\), it does not represent a circle. Therefore, Statement 1 is **false**. ### Statement 2: The equation \( x^2 + y^2 + 4x + 6y + 13 = 0 \) represents a point. **Step 1: Rearranging the equation** We start with the equation: \[ x^2 + y^2 + 4x + 6y + 13 = 0 \] We can rearrange it to group the \(x\) and \(y\) terms: \[ x^2 + 4x + y^2 + 6y + 13 = 0 \] **Step 2: Completing the square for \(x\)** For the \(x\) terms: \[ x^2 + 4x = (x + 2)^2 - 4 \] **Step 3: Completing the square for \(y\)** For the \(y\) terms: \[ y^2 + 6y = (y + 3)^2 - 9 \] **Step 4: Substitute back into the equation** Substituting these back into the equation gives: \[ ((x + 2)^2 - 4) + ((y + 3)^2 - 9) + 13 = 0 \] This simplifies to: \[ (x + 2)^2 + (y + 3)^2 - 4 - 9 + 13 = 0 \] \[ (x + 2)^2 + (y + 3)^2 = 0 \] **Step 5: Conclusion for Statement 2** The equation \((x + 2)^2 + (y + 3)^2 = 0\) implies that both squares must equal zero, which means: \[ x + 2 = 0 \quad \text{and} \quad y + 3 = 0 \] Thus, \(x = -2\) and \(y = -3\). This represents a single point \((-2, -3)\). Therefore, Statement 2 is **true**. ### Final Conclusion: - Statement 1 is **false**. - Statement 2 is **true**.

To solve the given statements, we will analyze each statement step by step. ### Statement 1: The equation \( x^2 - y^2 - 4x - 4y = 0 \) represents a circle with center (2, 2) passing through the origin. **Step 1: Rearranging the equation** We start with the equation: \[ ...
