Anyone know what the gradient means? Does it just simply mean the SLOPE (2/1) ?? OR is it reffering to something else? If so, any info would be helpful. I did a quick search on wikipedia and Im stil stumped. THANKS!!

Yes, gradient and slope refer to the same thing with regards to functions.

Note that for linear equations the "gradient" (I would say "derivative") is a constant and is the same as the slope of the line. For nonlinear equations, the derivative at every point is equal to the slope of the tangent line at that point. That's some times used as the definition of "gradient".
