Explain what it means to have a correlation in a scatter plot.

The relationship between the two variables is known as correlation. If the points are close to each other and making a straight line in the scatter plot, then two variables are said to have a high correlation. If the points are equally distributed in the scatter plot, the correlation is said to be low, or zero.

Step-by-step explanation:

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.
