b= 8 because when you plot the point the interception in y is 8 m= -5 because is rise/run that means you have to go down 5 and 1 to the right, that is your slope
9 x² + 16 y² = 144 /:144 General formula of ellipse ( the center is at the origin ): a² = 16, b² = 9 Domain: [-a, a ] = [-4, 4] Range:[-b, b ] Answer: B ) ellipse. Domain: { -4 ≤ x ≤ 4 } Range: { -3 ≤ y ≤ 3 }
