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.......!!!!
