Solve the system of equations using substitution 4x-2y=8 y= 1/2x+2

Step-by-step explanation:

To solve this system of equations using substitution, you must substitute the second equation into the first equation and solve for x, as you can see below:

Now you must substitute the value of x into the second equation to find y, then:

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.
