Which does not show a direct variation between x and y?

a. y=5x

b. y=6/x

c. y=0.7x

d. y=x9/20

i it is d but iam not good at math

The one that does not show a direct variation is that answer B because I notice that letters A, C, and B have slopes and that the function is equal to kx, making it a direct variation. But on the answer B, the function y = 6/x is a indirect variation, making it equal to xy = 6.

M< 5 = 80 , < 2 = 80, < 6= 100, < 3= 100, < 7= 80, < 4= 80, < 8= 100
