Question

Which of the following is a true statement?

Answer 1

B. Is true. Because if you were to multiply the number you would get these answers.

Answer 2

Option: D is the correct answer.

The k-value is:
`(-1)/(4)`

Explanation:

The table of values of x and y are given as follows:

x y

-4 1

8 -2

12 -3

20 -5

We know that x and y are said to be in proportional with constant of proportionality k if there is a constant k such that:

`y=kx`

for different ordered pair (x,y)

Here for ordered pair (-4,1) we have:

`1=k* (-4)\\\\i.e.\\\\k=(-1)/(4)`

Similarly for all the other ordered pair we get:

k is a constant and

`k=(-1)/(4)`

Hence, the answer is:

Option: D
