Study Notes
Slope and Rate of Change
- Slope is a measure of how steep a line is.
- Rate of change is defined as the change in output (y) over the change in input (x).
Direct Variation
- Direct variation is a relationship between two variables in which one variable is proportional to the other.
- In the equation for direct variation, y = kx, where 'k' represents the constant of proportionality or the slope of the line.
Equation Notation
- In the equation y = mx + b, 'm' typically represents the slope of the line.
- In the equation y = kx, 'k' represents the slope or the constant of proportionality.
