If the point (12, 4) lies on the graph of a direct variation, what is the constant of variation?
a. 8
c. 3
b.1/3
d. 48

Option B is the constant of variation.

Step-by-step explanation:

Given direct variation points .

Lets assign to .

And we know that in direct variation if one value increases other also increases or vice versa.

Where we can say that coordinate points can be shown as

is the constant of variation or the constant of proportionality.

So plugging the values of and .

Dividing both sides with .

So the constant of variation is and option B resembles the same.
