Final answer:
Finding the values of x and y usually requires substituting the given x value into an equation and solving for y. However, without specific details of the points or the equation, one cannot provide exact coordinates.
Step-by-step explanation:
The student is asking for the values of coordinates at specific points in a given context, likely related to a graph or frame of reference. Since the details of points A, B, and C are not provided, an accurate answer cannot be given directly. However, finding the values of x and y typically involves substituting the given value for the independent variable into an equation and solving for the dependent variable. For instance, in a quadratic equation where a, b, and c are constants, you could use the quadratic formula to find the solutions for x. When given a frame of reference, determining the position of one point relative to another requires assessing the given coordinates and translating them according to the new origin. In physics, y could represent position and x could represent time, so you would substitute the given time into the equation to find the position.
