Question

A 9 feet tall dragon ice sculpture is melting at a rate of 1.75 feet per hour. Write a linear function that represents this scenario.

Answer 1

`y = 9 - 1.75x`

Explanation:

Given

`Initial\ Height = 9ft`

`Rate = 1.75ft` per hour

Required:

Determine the linear function

Let y represent the function and x represent the number of hours

The function can be represented with:

`y = Initial\ Height- Rate * x`

We used minus (-) in the equation because the question indicates that the height of the sculpture reduces.

So, we have:

`y = 9 - 1.75 * x`

`y = 9 - 1.75x`
