y = (some function of x). Since you've not given us the graph no-one can be any more helpful than that!
an equation with more than one operation
the question does not make sense to make a graph; you need an equation, that means there must be an equals sign. (or an ordering, that means using a greater than sign like this > or a less than sign like this< )
Yes
its not the equation that matters it is how you map it out on the graph, the vertical and horizontal axis are interchangeable. For example if x is the vertical axis and y is the horizontal axis the graph would look different than if y was the vertical axis and x was the horizontal axis. The narrow and wide of a graph depend on the horizontal axis ( how quickly the numbers increase and or how far apart the markers are spaced) ...If the intervals are counted by 5 the graph would be wider than if the intervals were counted by 500.
visually.
A graph can be more useful for making presentations because it is more visual, and it can be easier to recognize a pattern in a graph for the same reason. However, a graph doesn't have any more data than a table with the same data.
A graph allows you to visualize how the numbers fit together and makes spotting something like an asymptote easy to find.

Yes, but it could be very difficult to interpret the graph. However, if some of the variables were qualitative or binary, it would not be too bad.
Yes, because you can rewrite it as: y = -x/10 Which is a line. When you graph the above equation, the graph passes the vertical line test - meaning that the graph never intersects with any vertical line more than once.
The graphical way is probably the simplest. Draw a graph of the equation. Hold a ruler parallel to the y axis and slide it from left to right. If, at any point, the ruler touches the graph at more than one point then you do not have a function.
Because a bar graph and pictographs are more visual and labelled than any other type of graph.
3s=2t can also be written as 3y=2x or 3x=2y. Either way, it is linear. To find out if it is linear, simply graph it. If you can draw a completely vertical line through any point of the graph without intersecting more than one point of the graph, then it is linear. This equation (3s=2t), it is linear.
It is a straight line equation in the form of: y = -2x+6
an equation with more than one operation
No, this is not a function. The graph would have a vertical line at x=-14. Since there are more than one y value for every given x value, the equation does not represent a function. The slope of the equation also does not exist.
