Quizplus · Accepted Answer

Since y is directly proportional to x, the relationship between y and x can be expressed as $y = kx$, where k is the constant of proportionality. Given $x = 5$ and $y = 24$, we can find k by substituting these values into the equation, resulting in $24 = k \cdot 5$. Solving for k gives $k = \frac{24}{5}$. Therefore, the linear model that relates y and x is $y = \frac{24}{5}x$.
