Which transformation is shown by the coordinates below?

L(-1, 9) M(-8, 8) N(-3, 5)
L'(-9, -1) M'(-8, -8) N'(-5, -3)

a Reflection over the x-axis
b Translation 8 units left and 8 units down
c Rotation 90 degrees clockwise
d Rotation 270 degrees clockwise

Its a

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.

14 ft 7 inches

step-by-step explanation:

since each model inch corresponds to 25 real inches, 7 model inches will correspond to

7×25" = 175"

at 12" per foot, that is 14 feet, 7 inches.
