Is this equation a function -x plus y equals -4?
Yes it is a function. In standard form it is y=x-4.
Is the equation y equals 0 a function?
Yes, none of the X values repeat, therefore it is a function. X=0 is not a function though.
Is x squared plus 5y minus x equals 7 a function?
No. It is an equation. A function would link the variable x to another variable - possibly denoted by y. It is a relationship between two (or more) variables.
