A graph is more informative than an equation because a graph is easier to interpret visually, and find all the points and line them up, rather than just a slope which shows no points(data).
y = (some function of x). Since you've not given us the graph no-one can be any more helpful than that!
An example of an equation with a degree greater than 1 is (y = x^2 - 4x + 4). This is a quadratic equation, and its graph is a parabola, which does not produce a straight line. Since its highest exponent is 2, it is classified as degree 2, and the graph will show a curved shape rather than a linear one.
The equation representing the relationship described is ( y = \frac{1}{2}x + 3 ). This linear equation indicates that for every value of ( x ), the corresponding ( y ) value is three units more than half of ( x ). The graph of this equation will be a straight line with a slope of ( \frac{1}{2} ) and a y-intercept at ( (0, 3) ). Thus, the correct graph will show a line that slopes upward, starting at the point (0, 3).
an equation with more than one operation
Yes
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.
Because a bar graph and pictographs are more visual and labelled than any other type of graph.
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.
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.
an equation with more than one operation
It is a straight line equation in the form of: y = -2x+6
