No, because the gradient of the line becomes infinite. Infinite gradient is equivalent to infinite acceleration at that point. Infinite acceleration (by Newton's Laws) would require infinite force.
No. A vertical line on a speed/time graph would indicate that the object's speed changed from one value to another in zero time. Another way to describe it would be to say that it had infinite acceleration. Neither description is physically possible.
The variable plotted along the vertical axis is the distance in the first case, speed in the second. The gradient of (the tangent to) the distance-time graph is the speed while the area under the curve of the speed-time graph is the distance.

Measuring a lawn Calculating the speed of a falling object
speed = distance / time
If a graph shows distance on the vertical axis and time on the horizontal axis, and the speed is steadily increasing, the line representing speed will be a straight line.
with regard to question 16 above could any part of the speed line ever become perfectly vertical

Airspeed, altimeter, and vertical speed.
Assuming that the question refers to a speed-time line, the answer is no. It would require the object to be travelling at infinite speed and, to be accelerated to an infinite speed would require an infinite amount of energy.
A graph shows distance on the vertical axis and time on the horizontal axis. If the speed is steadily increasing, what will the line representing speed look like on the graph? Could any part of the speed line ever become perfictly vertical? why or why not
'Vertical velocity' means speed up or down.
The value of the vertical speed at the highest point of the projectile's trajectory is the lowest speed at the maximum height reached.
Speed = distance / time A line graph with distance on the vertical axis and time on the horizontal axis could be used to determine speed. The speed would equal the slope of the line. Alternatively, a line graph with distance/time on the vertical axis and time on the horizontal axis would show speed. The acceleration would equal the slope of the line.
Not curved.
Zero.
