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 1:50 identifying constant of proportionality graphically bonus question

Explanation:

Step1: Recall formula for constant of proportionality

For a proportional relationship $y = kx$, $k=\frac{y}{x}$.

Step2: Select a point on the graph

The graph passes through the point $(4, 3)$.

Step3: Calculate the constant of proportionality

$k=\frac{y}{x}=\frac{3}{4}= 0.75$

Answer:

$0.75$
