Slope of a straight line = (y1-y2)/(x1-x2)
Slope of a straight line is the same at all points on the line, whereas for a curved line it changes.
The slope between any two points on a straight line is constant because a straight line represents a linear relationship between the two variables. This means that the rate of change remains consistent regardless of which two points you choose on the line. Mathematically, the slope is calculated as the change in the vertical direction (rise) over the change in the horizontal direction (run), and for a straight line, this ratio does not vary. Therefore, the slope remains the same for all pairs of points on that line.

Slope of a straight line = (y1-y2)/(x1-x2)
The straight line with no slope is a point
A slope is 0 if it is a straight horizontal line. A slope is undefined if it is a straight vertical line.

-- If the position/time graph is a straight line, then the speed is constant, and the slope of the line is the average speed, as well as the instantaneous speed at any moment. -- If the position/time graph is not a straight line, then the average speed between two moments in time is the slope of a straight line drawn between those two points on the graph.
the formula for slope is y=mx+b, a horizontal line has the slope of zero and the slope of a vertical line can be answered as undefined
If it is a straight line, then yes.
