Answer:
Explanation:
For direct variation equations, we have the general outlook as:
[tex]a\text{ = }\frac{b}{d}\cdot c[/tex]
What this simply means is that we have to multiply every instance of the independent variable (c in this case) with a constant ratio or proportionality ratio (b/d in this case) to get the instance of the dependent variable (a in this case)
a) For the first equation, we do not have a direct variation. The reason for this is that there is no constant term that relates to the terms of the dependent variable. The correct choice here is non-proportional
b) For the second fu
