Question

How do you find the constant of variation?

Answer 1

The constant of variation in a direct variation is the constant (unchanged) ratio of two variable quantities.

The formula for direct variation is : y=kx or k=y/x

Answer 2

i still dont get it... can i show you the problem?

Answer 3

sure

Answer 4

What the question?

Answer 5

i just drew it

Answer 6

yes but what exactly do you need to find?

Answer 7

constant of variation

Answer 8

Ok then the constant of variation is k
k=y/x
so you divide the y-values by the x-values

Answer 9

all of them?

Answer 10

together

Answer 11

To get the constant of variation of all the numbers you add all the y's and then add all the x's and then divide the total amount of y's by the total amount of x's

Answer 12

so 37/15?
