Fiona earns $2/hour more than Philip.

Step-by-step explanation:

y = 12x shows a slope of 12. That slope is the hourly salary.

Philip earns $12/hour.

Fiona:

$42/(3 hours) = $14/hour

Fiona earns $14/hour

14 - 12 = 2

Fiona earns $2/hour more than Philip.

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.
