A straight line with a positive slope on a position-time graph is the graph of an object that's moving in a straight line with constant speed.
An undefined slope is just a line straight down. The slope is undefined.
a verticla line
A straight line cannot have two slopes. A curve, however, might have a different slope at every different point.
The horizontal line represents that the acceleration is zero or constant speed and the line that slopes downward means that the object is slowing down and it is a negative acceleration.

a verticla line
Yes it can, but it would not then be a straight line but an angle.

can a line have two slopes
On a graph of speed versus time, where time is plotted along the horizontal (X) axis and speed along the vertical (Y) axis: -- constant speed (zero acceleration) produces a straight, horizontal line; -- constant acceleration produces a straight, sloped line; the slope of the line is equal to the acceleration; -- if the acceleration is positive, the line slopes up to the right (speed increases as time increases); -- if the acceleration is negative, the line slopes down to the right (speed decreases as time increases).
If the slopes of a straight line equation are the same but with different y intercepts then they are parallel.
positive slope, the line goes up (increases) from left to right negative slope, the line goes down (decreases) from left to right zero slope, the line is horizontal (flat) undefined slope, the line is vertical (straight up)
On a distance-time graph, different constant speeds would be represented by straight lines which have different slopes. The steeper the line, the faster the speed. Each line would have a constant slope to indicate a constant speed.
Cathode rays create straight-line motion. They are streams of electrons that travel in a straight line from the cathode to the anode in a vacuum tube.
