Since y is directly proportional (direct proportion) to x, the value of x when y = -7.93 is equal to 1.3.
<h3>What is a direct proportion?</h3>
Mathematically, a direct proportion is also referred to as direct variation and it can be represented with the following mathematical expression:
y = kx
Where:
- y and x are the variables.
- k represents the constant of proportionality.
Since y varies directly (direct proportion) with x, the variable x and y must remain in a constant ratio.
Next, we would determine the constant of proportionality (k) as follows:
Constant of proportionality (k) = y/x
Constant of proportionality (k) = 12.2/-2
Constant of proportionality (k) = -6.1
Now, we can determine the new value of x as follows:
k = y/x
x = y/k
x = -7.93/-6.1
x = 1.3
