Question

Jana earns $25 per week for mowing the lawn and deposits the money into her savings account. The amount of money in Jana’s account can be represented by the equation y=25x + 125, where x is the number of weeks she has been mowing the lawn. What does the y-intercept of the graph represent in this situation?

Answer 1

The y-intercept represents the initial money that Jana has in his account.

Explanation:

Given the equation of line is
`y=25x + 125`.

Also, Jana earns $
`25` per week.

And
`x` is the number of weeks she has been working.

If we plug week
`x=0` in the equation
`y=25x + 125`. It will give us the y-intercept.

That means the amount of money in Jana's account before she began mowing lawns.

The y-intercept represents the initial money that Jana has in his account.
