Justin is considering two websites for downloading music.The costs are detailed here:
Website 1: a yearly fee of $30 and $1.50 for each download
Website 2: $2 for each download.
What is a system of equations to represent the costs for one year? Express your equations in the form of y=mx+b where x is the number of downloads for the year and y is the total cost for the year.

Please, Please help me! I am so confused on this one! Thanks!
