How do you match equations and graphs?
Observe the Graph, identify whether the slope is positive or negative. Identify 2 points on the graph Using your 2 points, find the slope Look at your options, which functions match the slope you calculated (the m in y=mx+b) Plug in your points. If you plug in x and y is your answer, its a match.
