Final answer:
Insufficient context is provided to accurately determine the values of x(-9, 2) and y(5, -4). The details suggest a statistical or algebraic problem, but the connection between the formulas and the coordinate points is not made clear.
Step-by-step explanation:
To find the values of x(-9, 2) and y(5, -4), we must understand the context given in the several pieces of information provided. However, there are insufficient details as to how the values were initially obtained for each of these points, as various formulae are mentioned without a direct connection to the question. For example, the quadratic formula is used with constants a, b, and c, but it is unclear how this is related to the coordinates given. Accordingly, without additional information, we cannot accurately determine which of the given answer choices is correct.
The mention of lines of best fit and the quadratic equation suggests a problem related to data fitting or statistical analysis, possibly involving regression. Still, without a clear understanding of the methods used to obtain 'x' and 'y', or the interpretation of x(-9, 2) and y(5, -4), an accurate answer cannot be derived. Thus, I am unable to verify the correctness of the provided answer choices.The values of x(-9, 2) and y(5, -4) rounded to the nearest hundredth are:a) x(-9, 2) ≈ (-8.06, 1.85); y(5, -4) ≈ (4.47, -3.74)
