This is not a direct variation, because it cannot be written in the form y = kx
This is a direct variation, because it can be written as xy = -10
where k = 0.
This is a direct variation, because it can be written as y=-1/10x, where k=-1/10
This is a direct variation, because it can be written as y = -10x
where k = -10.
This cannot be determined
Please help me out this is a important question
