It tells you that the two variables in the graph change together at the same rate. There may or may not be a causal relationship between the tw variables: both could be related to a third variable which is not part of the graph.
The rate of change on that line. This is called the tangent and is used in the application of the derivative.
You can't determine velocity from that graph, because the graph tells you nothing about the direction of the motion. But you can determine the speed. The speed at any moment is the slope of a line that's tangent to the graph at that moment.

No. The slope on a speed vs time graph tells the acceleration.

"Slope" is the steepness of the line on any graph.

It is the legend or key.
A continuous graph that shows change over time.
No. The slope on a speed vs time graph tells the acceleration.
For motion at constant speed along a straight line, the acceleration is zero.

line graph
If the graph if speed vs. time is a straight line parallel to the time axis, then the speed is not changing.Acceleration is the slope of the line on such a graph. Slope is (speed change) divided by (time for the change).Since the speed doesn't change over any period of time, the slope of the line is zero.The object's speed is constant. Its acceleration is zero.
