    When I came across the explanation of this standard and then saw the example I was a little thrown off. The standard talks about a quadratic and linear equation but the example talks about a circle and a linear equation. When the word “quadratic” was used was it meant to pertain to any second degree equation? If so, could I use an ellipse or a hyperbola in place of the circle and have it still align to the standard?

    Thanks,
    Dave

    Sorry, I don’t know how I missed this one, thanks for bringing it to the front again. Yes, the equation for an ellipse or a hyperbola is a quadratic equation, so is included in this standard.
