Here's how to find the asymptote with a positive slope:\r \n" ); document.write( "\n" ); document.write( "1. **Simplify and rearrange the equation:**\r \n" ); document.write( "\n" ); document.write( " -4x² + y² - 2y = -3y² + 8x + 9y + 15 \n" ); document.write( " -4x² - 8x + 4y² - 11y - 15 = 0 \n" ); document.write( " -4(x² + 2x) + 4(y² - (11/4)y) = 15 \n" ); document.write( " -4(x² + 2x + 1) + 4 + 4(y² - (11/4)y + (121/64)) - 121/16 = 15 \n" ); document.write( " -4(x + 1)² + 4(y - 11/8)² = 15 - 4 + 121/16 \n" ); document.write( " -4(x + 1)² + 4(y - 11/8)² = 11 + 121/16 \n" ); document.write( " -4(x + 1)² + 4(y - 11/8)² = (176 + 121)/16 \n" ); document.write( " -4(x + 1)² + 4(y - 11/8)² = 297/16\r \n" ); document.write( "\n" ); document.write( "2. **Divide to get the standard form:**\r \n" ); document.write( "\n" ); document.write( " -(x + 1)²/(297/64) + (y - 11/8)²/(297/64) = 1 \n" ); document.write( " (y - 11/8)²/(297/64) - (x + 1)²/(297/64) = 1\r \n" ); document.write( "\n" ); document.write( "3. **Identify the center and the values of a and b:**\r \n" ); document.write( "\n" ); document.write( " The center of the hyperbola is (-1, 11/8). \n" ); document.write( " a² = 297/64, so a = √(297/64) = (3√33)/8 \n" ); document.write( " b² = 297/64, so b = √(297/64) = (3√33)/8\r \n" ); document.write( "\n" ); document.write( "4. **Find the equations of the asymptotes:**\r \n" ); document.write( "\n" ); document.write( " The equations of the asymptotes for a hyperbola in the form (y-k)²/a² - (x-h)²/b² = 1 are given by:\r \n" ); document.write( "\n" ); document.write( " y - k = ±(a/b)(x - h)\r \n" ); document.write( "\n" ); document.write( " In our case: \n" ); document.write( " y - 11/8 = ±((3√33)/8 / (3√33)/8)(x + 1) \n" ); document.write( " y - 11/8 = ±1(x + 1) \n" ); document.write( " y = ±(x+1) + 11/8\r \n" ); document.write( "\n" ); document.write( "5. **Asymptote with positive slope:**\r \n" ); document.write( "\n" ); document.write( " We want the asymptote with the positive slope, so we take the positive sign:\r \n" ); document.write( "\n" ); document.write( " y = x + 1 + 11/8 \n" ); document.write( " y = x + 19/8\r \n" ); document.write( "\n" ); document.write( "So, the equation of the asymptote with a positive slope is y = x + 19/8. \n" ); document.write( " \n" ); document.write( " |
