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
