Yes, it is direct variation.
The question is not clear. But if you want this in the form y=kx, then k must be 1.5

The equation is xy = 5*9 = 45 Alternatively, y = 45/x
Yes, it is direct variation.
No, it is not a direct variation.
No.
y=7x
No, this is an inverse variation.

Direct
No.
No, it does not.
Yes
Y varies in direct proportion to x.
y = 5x + 1 is nota direct variation.y = 5x + 1 is nota direct variation.y = 5x + 1 is nota direct variation.y = 5x + 1 is nota direct variation.
