do x and y have a proportional relationship? yes no write an equation for the relationship between x and y…

Explanation:

Step1: Check proportionality

A proportional relationship has the form $y = kx$ and passes through the origin $(0,0)$. The graph passes through $(0,0)$ and is a straight - line. So, $x$ and $y$ have a proportional relationship.

Step2: Find the constant of proportionality $k$

We can use the formula $k=\frac{y}{x}$. Let's take a point on the line, say $(1,15)$. Then $k = \frac{y}{x}=\frac{15}{1}=15$.

Step3: Write the equation

The equation for a proportional relationship is $y = kx$. Since $k = 15$, the equation is $y=15x$.

Answer:

yes $y = 15x$
