Slope is a really cool idea that helps us understand how lines look on a graph! Here are some important things to know about slope:

• What is Slope?: Slope tells us how steep a line is. We can think of it like this: it’s the change in $y$ (up and down) compared to the change in $x$ (side to side). We can write it as $m = \frac{\Delta y}{\Delta x}$.

• Positive Slope: If the slope is positive, that means the line goes up when you move from left to right. You can imagine it like climbing a hill!

• Negative Slope: A negative slope shows that the line goes down from left to right. It’s like sliding down a slide.

• Zero Slope: A zero slope means the line is flat and doesn’t go up or down. This shows that $y$ stays the same no matter what happens to $x$.

When we understand slope, we can better analyze different situations in the real world and make good predictions. So, let’s start graphing and learn even more!
