Answer:
C. Direct variation; y = 6x
Step-by-step explanation:
Let's determine what direct and inverse variation are:
- Direct: y = kx, where k is any constant
- Inverse: y = k/x, where k is any constant
Here, let's look at the relationship between x and y. The first column is x = 1 and y = 6, so let's put that into y = kx and try:
y = kx
6 = k * 1
k = 6
Does this pattern continue? Check with the second column:
y = 6x
12 =? 6 * 2
12 = 12
This does work, and if you try all the other columns, they provide true statements, as well.
Thus, the answer is direct variation because y = 6x is of the form y = kx, and the equation is y = 6x because for every value of x, the y is 6 times that x value. The answer is C.
