degrees each hour. Which equation shows the temperature over time?

y=2x-8

Step-by-step explanation:

Fill the numbers of hours passed into z

E.g If 5 hours have passed

2(5)-8

10-8

=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.
