Study Notes
Slope in Mathematics
- The letter "m" is often used to denote slope in mathematics.
Calculating Slope
- Slope is calculated as the ratio of the vertical change (rise) to the horizontal change (run), often represented as rise over run or Δy / Δx.
Negative Rise
- A negative "rise" indicates that the line slopes downward, from left to right.
Measuring Steepness
- The steepness, incline, or grade of a line is measured by its slope (m).
Equation of a Line
- In the equation $y = mx + b$, the letter "b" represents the y-intercept, which is the point at which the line crosses the y-axis.
