To understand positive and negative slopes on graphs, let's make it simple.

1. Positive Slope: When a line goes up as you move from left to right, it has a positive slope.

Think about hiking up a hill. As you walk upwards, you gain height.

For example, if you have the equation (y = 2x + 1), the line goes higher as you go to the right.

2. Negative Slope: On the other hand, if a line goes down as you move from left to right, it has a negative slope.

This is like walking downhill.

An example would be the equation (y = -3x + 4). This line goes lower as you move to the right.

In short, just look at the line's direction:

• If it goes up, it is a positive slope.
• If it goes down, it is a negative slope!
