The slope is 9 because we use the equation (y2-y1)/(x2-x1)
(7+2)/(-6+7)
=9/1 =9
All of the above I believe
It means that the satellite's orbital period is equal to the Earth's rotation period ... roughly 23 hours 56 minutes 4 seconds ... so that the satellite always stays over the same longitude.
IF that satellite's orbit has also been carefully placed over the equator, THEN the satellite is in a 'geostationary' orbit. It appears motionless in the sky, and can be used to sell 900 channels of TV to people with little dishes that they never need to move.
The moon has craters,yes moon have rocks,No the moon has neither traveler dirt it's just a giant round rock,No the moon doesn't have ice because it's gravity can't hold onto things like water,No volcanoes or geysers.
