Review: Key Concepts .
The equation of a linear function in slope-intercept form is written as
y = mx + b, where mand b are real numbers, m is the
and b is the
y-intercept of the line
.
Changing the value of b moves the graph
or
Changing the value of m affects the
and whether the line
slopes up or down from left to right.

m=slope

up or down

steepness

Step-by-step explanation:

Not really much to explain here you could've found this stuff on khan academy or math is fun to be honest lol

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.
