Answer:

inverse variation

Step-by-step explanation:

direct variation

y =xk

inverse variation

xy =k

Lets see if the data fits either

(4,25)  and (5,20)  and (10,10) are three points

direct variation

y/x = k  which is a constant

10/10=1  does not equal 20/5=4  so it cannot be direct variation

inverse variation

xy =k

4*25 =100   5*20 =100   10*10 =100

This is a constant  so it is inverse varaiton
