I need an answer for this really fast!! Lin notices that the number of cups of red paint is always 2/5 of the total number of cups. She writes the equation r=2/5t to describe the relationship. Which is the independent variable? which is the dependent variable? Explain how you know

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.

is means division by fractions

step-by-step explanation:

is should be y = 5x
