Please help me with this question.. please.

y= 30,000x - 2000
y= -2000x +30,000

y = -2000x + 30,000 is the correct answer.

Step-by-step explanation:

For slope intercept equation we first determine the intercept on the axis.

The intercept is a constant value, c, in the slope intercept equation.

In this case, the constant value is 30,000.

Our height, y, is directly proportional to minute,x, taken to descend.

y = mx + c

M is the slope/ gradient which is -2000 since the airplane is descending.

Since the plane descends 2000 feet per minute, its height after 1 minute should be:-

y = -2000(1) + 30,000

y = 28,000

This calculation confirms our above answer.
