Answer:
For part one 30000 and the slope for part two is -2000 and for part three it is y=30000=2000x.
Step-by-step explanation:
If it starts at 30,000 then that is on the 0 on the x-axis.
While the plane is descending by 2000 so that is the slope but because it is descending and not rising it is -2000. If it was rising it would be 2000.
And for part three because it starts and 30000 and it goes down 2000 by the x-axis.
Hope this helps.
