Question

the total cost of online streaming is proportional to the number of months. what is the constant of proportionality? online streaming of tv shows/movies

Explanation:

Step1: Recall the formula for proportionality

The equation for a proportional relationship is $y = kx$, where $k$ is the constant of proportionality. We can choose a point on the line, say $(x = 2,y = 30)$.

Step2: Substitute values into the formula

Substitute $x = 2$ and $y = 30$ into $y=kx$. We get $30=k\times2$.

Step3: Solve for $k$

To find $k$, divide both sides of the equation $30 = 2k$ by 2. So, $k=\frac{30}{2}=15$.

Answer:

15
