The **slope-intercept form** of a linear equation is:

\[
y = mx + b
\]

where:
- \(y\) is the dependent variable,
- \(x\) is the independent variable,
- \(m\) is the **slope** of the line, which represents the rate of change of \(y\) with respect to \(x\),
- \(b\) is the **y-intercept**, which is the value of \(y\) when \(x = 0\). It represents the point where the line crosses the y-axis.

This form is useful because it directly provides both the slope of the line and the y-intercept, making it easy to graph the equation and understand the line's behavior.

1. How do you find the slope and y-intercept of a line given two points?
2. What is the point-slope form of a linear equation, and how does it differ from slope-intercept form?
3. How do you determine if two lines are parallel or perpendicular using their slopes?
4. How can you convert a line from slope-intercept form to standard form?
5. What is the significance of the slope in real-world applications?

**Tip:** To find the slope-intercept form from a graph, identify the y-intercept first (where the line crosses the y-axis) and then calculate the slope by finding the rise over the run between two points on the line.
