**The Slope and Intercept of a Line**

The slope of a line is the ratio of change in a vertical distance over the change in a horizontal distance. It is denoted by m.Process to find the

**slope of a line**:

- We can take any two point on a line.
- Find the vertical change or change in y coordinate.
- Find the horizontal change or change in x coordinate.
- Find the ratio of these changes i.e.
**m = rise / run**

We have basically 4 types of slopes. These are:

**Zero Slope**: In this case the line is parallel to the x axis, The value of x is change or increased, the value of y remains constant or unchanged.

**Positive Slope**: In this case as the values of x increase, the value of y is also increased and the slope of a line is positive.

**Negative Slope**: In this case as the values of x increase, the value of y is decreased and the slope of a line is negative.

**No slope**: In this case the line is parallel to the y axis, The value of y is change or increased, the value of x remains constant or unchanged.
