The general formula for the polynomial function is
[tex]ax+by+c[/tex]Following this formula, you have to identify a, b and c in the given polynomial
[tex]-1+7x+\frac{1}{6}y[/tex]c is the term of the function that is not related to any variable, i.e. the number that is alone, so c = -1
a is the number that is related to the variable x, in the expression that value is a = -7
b is the number that is related to the variable y, in the expression that value is b = 1/6
