1. what is the slope of the line that passes through the pair of points? (5,2), and (7,8)

a. -3
b. 3
c. 1
d. -1

2. what is the slope of the line that passes through the pair of points? (3,-1), and (5,-8)

a. 7/2
b. 22/7
c. 7/22
d. -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.

true

i believe the answer is 323 ft
