1) The graph shows two lines, A and B. 
 A coordinate plane is shown with two lines, A and B, graphed. Line A has a slope of negative 1 and crosses the y axis at 5. Line B has a slope of positive 1 and crosses the y axis at 3. 
 How many solutions are there for the pair of equations for lines A and B? Explain your answer.
 2) Consider the following set of equations: 
 Equation A: y = 2x + 4
 Equation B: y = 3x + 1
 Which of the following is a step that can be used to find the solution to the set of equations?
 2x + 4 = 3x + 1
 2x = 3x + 4
 2x + 4 = 3x
 2x + 1 = 3x + 4
