4sqrt(5)

Step-by-step explanation:

Refer to photo for everything. Also, I didn’t do a lot of the algebraic steps on paper; try to do it yourself and see if you can get what I got. But, I did write out the process of finding the answer. I checked the answer with what was given and everything seems to work, but you should check yourself before using this answer just in case.

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.
