need help with these math problems that are division of u know how to do these please help!! (10 points)

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.

your answer would be 10x - 1

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:
