Speed is how fast you are going.
Velocity is almost the same but for one thing: it also includes what direction you are moving.
For example:
A car can have a speed of 50 mph, but a velocity of 30 mph northwards.

How can you determine the speed of an object that has constant motion if you have a distance vs time graph of the motion?
If constant motion means constant velocity then, total distance / total time = avg velocity => avg speed constant velocity => avg velocity = velocity
When does the slope of a position vs time graph yields?
Speed. More specifically... velocity.
What measures how fast an object is moving?
Acceleration is the rate of change of the velocity (speed) of an object. Acceleration is the derivative of the speed vs. time function.
What does a steep slope on a displacement vs time graph indicate?
The slope of the function on a displacement vs. time graph is (change in displacement) divided by (change in time) which is just the definition of speed. A relatively steep slope indicates a relatively high speed.
Is velocity the slope of the accerleration vs graph?
It's the other way around. The magnitude of acceleration is the slope of the graph of speed vs time.
Displacement vs. Time?
Displacement over time, or how far an object has moved in a given time, is the definition of speed. The difference between speed and velocity is that velocity has direction.
Does the horizontal line on the velocity vs time graph indicate a constant and positive acceleration?
Ahorizontal line on a velocity vs time graph does not indicate any acceleration because there is no slope. Speed remains constant.
What does the slope of a speed vs time graph represent?
magnitude of acceleration at every point on the graph
The slope of a speed vs time graph is equal to what?
Acceleration.
What does the slope of a distance vs time graph tell you?
Speed. Not "velocity" unless you also quote the direction of travel.
What does the slope of a time vs distance graph equal?
Slope of time Vs distance graph gives the inverse of velocity.
What is the biggest difference between speed and velocity?
velocity is speed with direction; velocity is a vector and speed is a scalar
