runs 140 meters in 5 seconds.

• Motion is a change in position measured by
distance and time.
• Speed tells us the rate at which an object moves.
• Velocity tells the speed and direction of a moving
object.
• Acceleration tells us the rate speed or direction
changes.
•
A distance-time graph tells us how far an object has moved with time.
•
The steeper the graph, the faster the motion.
•
A horizontal line means the object is not changing its position - it is not
moving, it is at rest.
•
A downward sloping line means the object is returning to the start.
• Time is always plotted on the X-axis (bottom of the
graph). The further to the right on the axis, the
longer the time from the start.
• Distance is plotted on the Y-axis (side of the graph).
The higher up the graph, the further from the start.
SOLUTION SET FOR TWO LINEAR
EQUATIONS
• ONE SOLUTION
• If a system of two variables has one
solution, then if you plug in the value
of that point in each of the equation, it
is true for both
• NO SOLUTION
• These two line have no solution because they
are parallel to each other and they do not
intersect
• INFINITE SOLUTIONS
• If two lines coincide then there exists infinite
solutions
