Write the equation of the circle with center (−1, −3) and (−7, −5) a point on the circle.

Step-by-step explanation:

The standard form of a circle is

We have everything we need to fill this in and solve for the radius.

 and

 and

so

Now we can write the equation using the center and the radius we just found:

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.
