Study Notes

Slope

The letter 'm' is often used to denote slope.
Slope is calculated by dividing the vertical change (rise) by the horizontal change (run), i.e., m = rise/run or m = Δy/Δx.
A negative slope indicates a downward slope, meaning as the input (x) increases, the output (y) decreases.

Measuring Steepness

The steepness, incline, or grade of a line is measured by its slope (m).

Equation of a Straight Line

The equation of a straight line is often written in the slope-intercept form, which is y = mx + b, where 'm' is the slope and 'b' is the y-intercept.
