Calculate slope as slope=(y2-y1)/(t2-t1).
If an x-t graph is a position-time graph, velocity is the slope of the line on the graph.
If you graph distance vs. time, the slope of the line will be the average speed.
Points: (x, y) and (x, y) Slope: y1-y2/x1-x2
You can use the formula: y=mx+b (berdill)

Speed (in the radial direction) = slope of the graph.

That's not correct. If you have a graph of distance as a function of time, the speed is the slope of the graph.
Using limits and the basic gradient formula: rise/run.
You can use the formula: y=mx+b (berdill)
Slope = change in y (distance) / change in x (time). If the graph is not a straight line then either apply the above formula to the tangent at the point of interest or differentiate the equation of the graph.
The slope for a straight line graph is the ratio of the amount by which the graph goes up (the rise) for every unit that it goes to the right (the run). If the graph goes down, the slope is negative. For a curved graph, the gradient at any point is the slope of the tangent to the graph at that point.
The slope of a velocity-time graph represents acceleration.
