Question

A hot air balloon is 500 feet up and is heading towards the ground at a rate of 3 feet per second how can you write this in slope intercept form?

Answer 1

A.
`y = -3x + 500`

Explanation:

Equation of the situation in slope-intercept form is given as
`y = mx + b`,

Where:

y = height of the balloon in the air (feet)

x = time (secs)

m = rate at which the balloon is heading towards the ground = -3

b = y-intercept, which is the starting value = 500

Substitute m = -3, and b = 500 into
`y = mx + b`

The equation would be:

✔️
`y = -3x + 500`
