Answer:

y=7x

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

we have the points (2,14) and (4,28)

Find out the constant of proportionality k

k=y/x                      

For (2,14) ----> k=14/2=7

For (4,28) ----> k=28/4=7

so                              

the value of k=7            

therefore                                          

The equation  is                                                    

y=7x
