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]
