Question

Which is the constant of variation, k, if y=kx, and y=3 when x=4?

3/4

4/3

3

4

Answer 1

The constant of variation, k, in the equation y = kx, is 3/4.

Step-by-step explanation:

The constant of variation, k, in the equation y = kx, represents the rate at which the dependent variable (y) changes with respect to the independent variable (x). To find the value of k, we can substitute the given values for y and x into the equation and solve for k. In this case, the equation becomes 3 = k * 4. Dividing both sides of the equation by 4, we find that k = 3/4.

Answer 2

k =
`(3)/(4)`

Step-by-step explanation:

given variation equation

y = kx

to find k substitute y = 3 and x = 4 into the equation and solve for k

3 = 4k ( isolate k by dividing both sides by 4 )

`(3)/(4)` = k
