What is the value of -5 and what is the value of 5

-5 is a negative number; if you plot it on the number line, it'll be 5 units to the left of the origin.  +5 is a positive number; it'll be 5 units to the right of the origin.

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.
