Question 659284: Tell whether the relationship between x and y is an inverse variation, If it is, Write an equation for it:
x 1 2 3 4 5 6 7 8 9 10
y 10 9 8 7 6 5 4 3 2 1
I think it is an inverse variation but I dont know how to write an equation for it.

You can put this solution on YOUR website!
If it was an inverse variation, then x*y = k for some fixed number k.

But 1*10 = 10

and

2*9 = 18

so the two pairs do NOT multiply to the same constant, which means that this relationship is NOT an inverse variation.
