## Slope of a line

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**

**Slope**= change in coordinate y / change in x coordinate

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.
