Does the equation 7x-4y=0 represent a direct variation? what is the constant of variation?

yes, k =

Step-by-step explanation:

The equation representing direct variation is

y = kx ← k is the constant of variation

rearrange 7x - 4y = 0 into this form

subtract 7x from both sides

- 4y = - 7x ( divide both sides by - 4 )

y = x ← in standard form

with k =

easy its decreasing

step-by-step explanation:

because its top point is at the to of the graph on the left side (atleast from the veiw i see it) now if that top point wast in the lower part of the graph it would be increasing hope this have a nice day
