An airplane 30,000 feet above the ground begins descending at a rate of 2,000 feet per minute. Write an equation to model the situation. What are the slope and Y-intercept?

Slope: -2000

Y-intercept: 30000

Equation: Y=-2,000x+30,000

Step-by-step explanation:

The pane starts at 30,000 feet, giving up an y intercept or a starting point. Since the plan is descending, you know the slop will be negative.

if you explain the the question more correctly i might be able to answer this better

step-by-step explanation:

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
