Tim explained a function in words and Paul wrote an equation.

Tim

The amount of money in a savings account increases at a rate of $225 per month. After eight months, the bank account has $4,580 in it.

Paul

y−1,400=56(x+26)

Whose function has the smaller y-intercept?

Tim’s with a y-intercept of $2,700
Paul’s with a y-intercept of $2,856
Paul’s with a y-intercept of $2,800
Tim’s with a y-intercept of $2,780

Tim's function has a y-intercept of $2,700, which is smaller than Paul's y-intercept of $2,856, Paul's y-intercept of $2,800, and Tim's y-intercept of $2,780. Therefore, Tim's function has the smallest y-intercept.
