HELP ME WITH MATH AND I WILL GIVE BRAINLEST FOR CORRECT ANSWER

They would use C. it shows 1/3 of the circle shaded this represents the 1/3 of the lasagna that was eaten last night, the other 2/3 is what was left over for them to eat later, so the answer is C.

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.
