The answer depends on what a is and on what element the slider changes.
change it to polar mode and then plot r = any constant
The slope is (change in 'y' produced by a change in 'x') divided by (change in 'x' that produces it). The slope of any horizontal line on the graph is zero because the value of 'y' is the same everywhere on the line. No matter how much you change 'x' along the line, 'y' never changes.
It is the derivative of the vertical change relative to the horizontal change - if the derivative exists. So, with the typical x-y graph, it would be dy/dx. If the graph is a straight line, then it is the change in the vertical positions between any two points divided by the change in the horizontal positions between the same two points (in the same order).
A continuous graph.
Any variables can be shown on a graph.
The slope at any point is the velocity, so you can construct a graph of that. The slope at any point on that graph is the acceleration. So you can construct a graph of that. The slope at any point on that is the rate of change of acceleration. And so on.
Yes you can Play any song and use the volume slider to change the volume.
change it to polar mode and then plot r = any constant
The slope of the tangent line in a position vs. time graph is the velocity of an object. Velocity is the rate of change of position, and on a graph, slope is the rate of change of the function. We can use the slope to determine the velocity at any point on the graph. This works best with calculus. Take the derivative of the position function with respect to time. You can then plug in any value for x, and get the velocity of the object.
The slope is the change in distance between any two points divided by the change in time between them.
deceleration can be measured from a velocity time graph by calculating the gradient of the velocity time graph if the V-t graph was linear. If the v-t graph was a curve then the differentiatial of the equation of the curve will give the deceleration variation with time.
The slope is (change in 'y' produced by a change in 'x') divided by (change in 'x' that produces it). The slope of any horizontal line on the graph is zero because the value of 'y' is the same everywhere on the line. No matter how much you change 'x' along the line, 'y' never changes.
if a function is increasing, the average change of rate between any two points must be positive.

Any graph can use percentages.
