1. Graph the following system of equations: y = x + 1 y = -x + 5 What is the solution to this system of equations?
2. Two friends, Alex and Ben, are saving money. Alex starts with $2 and saves $3 every week. Ben starts with $8 and saves $1 every week. The amount of money each friend has can be represented by the following equations, where y is the amount of money and x is the number of weeks: Alex: y = 3x + 2 Ben: y = x + 8 Graph these two equations. After how many weeks will Alex and Ben have the same amount of money? How much money will they each have at that time?
