Question 1159732: 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?

(0, y) with slope 225 and reaches (8, 4580)
slope is (4580-y)/8=225
so 4580-y=1800
y=2780
(0, 2780) has a y-intercept of $2780
the other function is y=56x+1456+1400
y=56x+2856
the y-intercept here is at (0. 2856), so the other function has the smaller y-intercept.
