HI!!

misty1212 · Answer

none are functions, but one is linear
the one with the $x$ in the numerator with no exponent

welshfella · Answer

a linear function  will have no  powers of x and /or y of 2 or above ( like x^ and/or y^2)  nor x  or y in a denominator of a fraction.

misty1212 · Answer

all of them are equations, none of them are functions

welshfella · Answer

can you identify a linear equation then?

welshfella · Answer

it will contain an x and a y  but neither must be in a denominator.

mathmale · Answer

Actually, ALL of these are functions.  Only one is a linear function.  Yes, the linear function is the 4th one, and the reasons for that are:  1) both x and y are in the first power, and 2) neither x nor y appears in a denominator.  The graph of this 4th function is a straight line, whereas the graphs of the others are not; the graph of y=x^2 is a parabola, for example.

It's already closed.
