Explain how the slope can indicate the direction of a line on a graph.

The slope of a line is like its mood – it tells you whether it's happy (going up) or sad (going down)! A positive slope means the line rises from left to right, indicating that as one variable increases, so does the other. Conversely, a negative slope shows the line descends, suggesting that as one variable increases, the other decreases. A slope of zero means the line is flat, signaling that there’s no change at all – it’s just chillin’! If you want to get even cooler with your slope understanding, remember that the steeper the slope, the more dramatic the change. A slope of 1 or -1 represents a one-to-one change, like climbing a staircase! Whereas a slope of 2 or -2 means for every step to the right, you take two steps up or down – whoosh! So, grab a graph and start plotting your visual story!
