Hmm, the expression is **8xyz** because there is no equal sign.

The other three:

**2y = 4x-6**

**y = 5**

**x = -4**

All three of the above are equations, but they are also linear functions as well, because there are no exponents on the x or y variables.
*For example,*

**2y = 4x ^{2 }-6** is not linear.

The way you used the term "Function Graph" is ambiguous to me. Usually a function is just a function, and you can decide to graph it or not. So for every function, there can be a function graph.

As a rule, I would only look at something and say "yeah, that's a function graph" if it was literally a graph of a function, i.e. you can see the x and y axis, and there are points, lines, and/or curves plotted on it.

thank-you

I direct many of my students to WolframAlpha website and also find it to be an excellent resource. I'm not exactly sure how to answer the above question beyond what James posted, the question could possibly be worded a little more clearly.
