How can you tell if an equation of a relation represents a linear relation?

    THanks to everyon who helps :)

    linear = first degree only, no squares, no cubes, no square roots,no products of variable.

    so x+3y=c is a linear equation
    x^3+y=c is NOT
    -x+12y=45 is linear
    1+ xy=c is NOT

    thanks so much that helped me a lot !!
