The curve defined by {{MATH_4}} is called a ``rotated ellipse.'' This is not a misnomer, as its graph below demonstrates. {{CMD_5}} {{ENV_6}} {{CMD_7}} Use implicit differentiation to find the derivative {{MATH_8}}. {{MATH_9}} {{CMD_10}} Using your answer, find the function {{MATH_11}} whose graph is the line tangent to the curve at the point {{MATH_12}}. {{MATH_13}} {{CMD_14}} {{CMD_15}} {{CMD_16}}
