Final answer:
The table must be filled by placing a value for 'x' and computing for 'y' using the equation y = 3x. Without additional information, it's unclear what value corresponds to cell A since the value for 'y' in that cell was not given. Clarification is needed to provide an accurate answer.
Step-by-step explanation:
To fill in the table using the equation y = 3x, you must replace the x in the equation with the value provided and solve for y. In this case, to find the value for cell A, we must identify which value of x corresponds to that cell in the table. The 'x' values given in the question (2, 3, 6 in the table) were replaced with those numbers and the corresponding 'y' values calculated (6, 9, 18 in the table). There seems to be a misunderstanding since the provided equation in the question is y = 3x, whereas the reference information discusses y = 9 + 3x, which is a different equation. Based on the correct equation y = 3x, if y in the table is given, then x can be found by dividing y by 3. Let's analyze the table provided in the question:
x | y
2 | 6
3 | 9
6 | 18
If we are to calculate the value for cell A when y is known, we divide y by 3. If 'y' is 6, then 'x' would be 2. If 'y' is 9, then 'x' would be 3. If 'y' is 18, then 'x' would be 6. If you are asking for a value that goes in cell A but have not provided what 'y' is supposed to be in cell A, then it's not possible to solve the problem unless more information is given.
