Direct proportion equations have the following form:
Where "k" is the Constant of proportionality.
In this case you know that "y" is directly proportional to "x" and when:
Having these values, you can substitute them into the equation and solve for "k":
So, substituting the value of "k" into the first equation shown above, you get that the equation that models the given relationship is:
Now, to find the value of "x", when the value of "y" is -24, you must substitute this value into the equation that models the relationship and then solve for "x". Then, you get:
Therefore, the answers are:
