When solving for k in an inverse proportion, what is the first step?

• A. Identify the variables involved
• B. Plug in numbers to the formula
• C. Graph the equation
• D. Find the slope of the line

Answer: (B)

In the context of solving an inverse proportion, the first step involves identifying the relationship between the variables involved. When working with inverse proportion, you start with the formula that defines the relationship, which typically takes the form of (y = \frac{k}{x}), where (k) is the constant of proportionality.

To solve for (k), it is crucial to identify the relevant variables and their relationships. This means looking at the values that you have or need to establish the connection between the varying quantities. It is only after identifying these variables that you can effectively plug in the numbers into the formula to calculate (k).

Thus, the correct approach is to start by identifying the variables. Once you have that understanding, you can substitute the known values to find (k).
