Question

money the graph shows a proportional relationship between a persons total savings in dollars and the number of weeks they have been saving. write an equation that models the savings. the equation y = \\(\square\\) models the savings.

Explanation:

Step1: Identify proportional slope

From the graph, at $x=10$ weeks, $y=500$ dollars. The slope $k = \frac{y}{x}$
$\frac{500}{10} = 50$

Step2: Write proportional equation

Proportional relationships follow $y=kx$, substitute $k=50$.
$y = 50x$

Answer:

$y = 50x$
