The equation would be y = -5/2x - 14. Since the slope and a coordinate pair was given, I used point slope form to figure out the equation.

Work:

y - 6 = -5/2 (x+8)
y - 6 = -5/2x - 20
+ 6 +6
______________
y = -5/2x - 14

A hot air balloon is currently at a height of 900 feet. The balloon is descending by 10 feet minute. Find a function for the bal

mylen [45]

Answer:

$y=-10x+900$

Step-by-step explanation:

Let

x -----> the number of minutes

y ----> the balloon's height in feet

we know that

The linear equation in slope intercept form is equal to

$y=mx+b$

where

m is the slope

b is the y-coordinate of the y-intercept

In this problem we have that

The slope is equal to

$m=-10\ \frac{ft}{min}$ ----> is negative because is a decreasing function

$b=900\ ft$

Remember that the y-intercept is the value of y when the value of x is equal to zero

In this context the y-intercept is the height of the balloon when the time is equal to zero (initial height)

substitute

$y=-10x+900$
