Explore the slopes and y-intercepts for a system of two linear equations.

a) Try to get the lines to be parallel, what do you notice about the slope? What is the solution?
b) Try to get the lines to cross once, what do you notice about the slope? What is the solution?
c) Try to get the lines to be parallel but a different y-intercept, what do you notice about the slope and y-intercepts? What is the solution?
d) Try to get the lines to be parallel and the same y-intercept, what do you notice about the slope and y-intercepts? What is the solution?
e) Review: Give the slope and y-intercept summary for the lines that would create each of these answers: No Solution, Infinite Answers, Exactly One Answer.
