Answer:
[tex]y = x[/tex]
Step-by-step explanation:
The top two are automatically eliminated because direct variation means NO y-intercept, and the graph of [tex]y = {x}^{2}[/tex]is a parabola, so this is out of the question. Now, the last two options are direct, but since it says direct linear variation, we want the less steeper graph, so in this case, [tex]y = x[/tex]is the graph we want. The rate of change [slope] of 12, makes the graph alot steeper.
* The 1 is unnecessary in the Slope-Intercept Formula.
