A.y=5x


B.y=6/x


C.y=0.7x


D.y=x9/20
  
please help i thank it is d but iam not good at math

Answer 1

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.
