Question

The linear function y=17x-24 models the relationship between the weekly profit in dollars,y, when the company sells x T-shirts. Which of these is the best interpretation of the y-intercept for this model

Answer 1

The y-intercept for the model is -24.

Explanation:

Given : The linear function
`y=17x-24` models the relationship between the weekly profit in dollars,y, when the company sells x T-shirts.

To find : Which of these is the best interpretation of the y-intercept for this model ?

Solution :

The general slope form of line is
`y=mx+b`

where, m is the slope

and b is the y-intercept

On comparing
`y=17x-24` with general form,

m=17 and b=-24.

So, the y-intercept for the model is -24.
