Question

What is the constant of variation, k, of the direct variation, y = kx, through (–3, 2)?

k = –
k = –
k =
k =

Answer 1

The answer is k= -2/3

Answer 2

Answer: k=
`(-2)/(3)`

Explanation:

Here, the equation of a line y=kx ------(1)

Since, According to the question this line passes through (-3,2)

Therefore, the point will be satisfy the equation of line.

Put x=-3 and y=2 in equation (1)

2=-3k

⇒ k =
`(-2)/(3)`

Thus, the required value of constant of variation, k=
`(-2)/(3)`
