Question

Which table shows a proportional relationship?

Answer 1

Number 4 is proportionality relationship

Answer 2

Answer:

Table N $1$

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $y/x=k$ or $y=kx$

In this problem the table N $1$ represent a proportional relationship

Find the value of k

$R/S=k$

For $R=5, S=1$

substitute

tex]k=5/1=5[/tex]

For $R=10, S=2$

substitute

$k=10/2=5$

For $R=15, S=3$

substitute

$k=15/3=5$

For $R=20, S=4$

substitute

$k=20/4=5$

For $R=25, S=5$

substitute

$k=25/5=5$

the equation of the proportional relationship is equal to

$R=5S$
