Note that we can use the first one to find a variation constant

 

y  = k (x )   

 

6.4  = k (4)      divide both sides by 4

 

6.4 / 4  =   k

 

1.6  = k

 

 

So......if this is true......then we should have  that

 

y  = 1.6x

 

Now....look at the second set of values  (x,y)  = (7, 11.2)

 

So......is this true??

 

11.2   = 1.6 ( 7)    yes!!!!

 

I think if you will check each of  the other  x values multiplied by the variation constant, you will end up with their associated y value......it might be good to practice this.......!!!!
