For a line, the ratio of the change in y to the change in x is the  of the line.

For a line, the ratio of the change in \( y \) to the change in \( x \) is the **slope** of the line. The slope, often denoted by \( m \), is calculated using the formula:

\[
m = \frac{\Delta y}{\Delta x} = \frac{y_2 - y_1}{x_2 - x_1}
\]

where \( (x_1, y_1) \) and \( (x_2, y_2) \) are two points on the line.

2. What does a zero slope indicate about a line?
3. What is the relationship between the slope and the angle of inclination of a line?
4. How can you find the slope of a line given an equation in point-slope form?
5. How do you determine the slope from a linear equation in standard form?

**Tip:** A positive slope indicates the line rises as you move from left to right, while a negative slope means the line falls.
