You can use the formula: y=mx+b (berdill)
Calculate slope as slope=(y2-y1)/(t2-t1).
On the standard Cartesian graph, horizontal lines have zero slope. They all have the equation Y = a number
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.
two ways : 1. calculate the slope of the two lines, if it is same, they are parallel. 2. draw a perpendicular line ( 90 degrees) from on of the lines and if it intersects the other line at 90degrees then they are parallel -HD

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

Points: (x, y) and (x, y) Slope: y1-y2/x1-x2
a stright line going acrossed the graph lines. :)
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.
downward as they proceed from left to right across a graph
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.
