<PRE><B>Question 1127345</B>
Interest each month is prt=500*0.02*1=$10.
She will get $10 each month, and this is a linear function, because each defined period is equal in time and the amount is equal as well.
The y-intercept is $500, for that is what she started with.
The function is f(x)=10x+500, where x=the number of months since the deposit.
The money will be 
500
510 after 1 month
520
530
540 after </PRE>
