find the slope of the line passing through the the following points: (−12, −56), (−57, 39).

slope of line = - 19/9

Step-by-step explanation:

Point A

Point B

Now slope of line (m) =

slope of line passing through points (-12, -56) and (-57, 39) is:

=

=

=

=

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.

the battle of gettysburg is considered the "high water mark" of the confederacy because it marked the greatest advance of the confederate forces against the union.
