Question

the following graph shows a proportional relationship. what is the constant of proportionality between y and x in the graph? constant of proportionality = related content constant of proportionality from graph

Explanation:

Step1: Identify a point on the line

The line passes through the point $(1,3)$.

Step2: Use the formula for constant of proportionality

For a proportional relationship $y = kx$, where $k$ is the constant of proportionality. We can find $k$ using the formula $k=\frac{y}{x}$. Substituting $x = 1$ and $y = 3$ into the formula, we get $k=\frac{3}{1}=3$.

Answer:

$3$
