Answer:

yes, k = [tex]\frac{7}{4}[/tex]

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 = [tex]\frac{7}{4}[/tex] x ← in standard form

with k = [tex]\frac{7}{4}[/tex]
