Ahot air ballon was at 2,180 feet. it decended at 120 feet per minute for 9 minutes. what is the balloons new height?

The balloons new height is

Step-by-step explanation:

Let

x ----> the number of minutes

y ----> the height of a hot air balloon in feet

we know that

The linear equation in slope intercept form is equal to

where

m is the slope or unit rate

b is the y-intercept or initial value

In this problem we have

The slope is equal to

---> is negative because is a decreasing function

The y-intercept is equal to

substitute

For x=9 minutes

substitute in the linear equation
