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.
