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
