Amber looks at the following system of equations. Y=-1/2 Y=1/3 She concludes that because there is no Y intercept value, the lines cannot intersect. Is Ambers conclusion correct? Explain your answer and support your reasoning with mathematical examples. Also how do you know your answer is reasonable? (Could you please use a graph to help me better understand? Thanks!)
