Consider the function represented by the equation x-y-4=0. what is the equation written in a function notation, with x the independent variable?

If x is the independent variable then y is the dependent variable so it would be y=something

you take x-y-4=0 and make it so that y is alone on one side

x-y-4=0

Add four to both sides

x-y=4

subtract x

-y=-x+4

divide by - 1 and get your answer

y=x-4
