Answer:
2. No it is not direction variation
3. This is direct variation with the constant being 2
Step-by-step explanation:
The equation for direct variation is y=kx
2. 8y = 3x+1
Divide each side by 8
8y/8 = 3x/8 + 1/8
y = 3/8 x + 1/8
We are adding 1/8 to each time so it is not direct variation
3. 12y = 24x
Divide each side by 12
12y/12 = 24x/12
y = 2x
This matches y= kx, where k=2
This is direct variation with the constant being 2
