Answer:
y = -90x + 2000
Step-by-step explanation:
Hello There!
So we need to write an equation of the line in slope-intercept form
y = mx + b
where m = slope and b = y intercept
They give us everything in the caption
They say that a hot air balloon descends from 2000 feet at a constant rate of 90 feet per minute
Descends from 2000 feet indicates that the hot air balloon starts at 2000 feet
Thus this is the y intercept
Descends indicates that the slope is going to be negative because descend means to go down
The hot air balloon descends at a constant rate of 90 feet per minute
Thus meaning that the slope is -90
Now that we have everything we add it all together and get that the equation is
y = -90x + 2000
hope this helps :)
