Study Notes
Slope Concepts
- Rise over Run: The basic definition of slope; measures the vertical change (rise) over the horizontal change (run).
- Slope-Intercept Form: The equation of a line represented as y = mx + b, where m is the slope and b is the y-intercept.
- Slope Formula: Defined mathematically as (y₂ - y₁) / (x₂ - x₁), used to calculate the slope between two points on a graph.
Line Characteristics
- Y-Intercept: The point where a graph intersects the y-axis, represented by the y-coordinate of that point.
- Standard Form: A linear equation expressed as Ax + By = C, where A, B, and C are constants.
- Horizontal Line: Has a slope of 0, indicating no vertical change as the x-value changes; not undefined.
- Vertical Line: Not a function; has an undefined slope due to no horizontal change as the y-value varies.
Graphing Techniques
- Effect of m on Slope: Larger values of m increase the slope's steepness, while smaller values decrease it.
- Perfectly Horizontal Lines: Possible to create, while perfectly vertical lines are not achievable in graphing.
- Finding Slope: Use the formula y₂ - y₁ over x₂ - x₁ to derive slope between two points.
- Basic Linear Equation: An example is y = x, which showcases a constant slope of 1.
Graphing Process
- First Graphing Step: Start by plotting the y-intercept as the initial point.
- Creating Additional Points: Use the rise over run method to establish other points on the graph.
- Connecting Points: Ensure that the line drawn between plotted points is straight for accurate representation of the function.
