Which set of ordered pairs does not represent a function? O {(9,3), (2,-2), (2,6), (-5,2)}
O{(-7,-5), (2, - 7),(-4,7), (7,5)}
o{(-1,-8), (0, -2), (9,6), (-3,-2)}
O {(1,0),(-1,9), (3, 2), (-7, -2)}

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.
