    Finding gradient using 2 points

    SL Core 2.1

    The gradient of the line is a measure of its steepness. It is calculated by measuring the rise (change in y) in the line over a certain run (change in x).


    The gradient of the line passing through the points (x1​,y1​) and (x2​,y2​) is

    m=x2​−x1​y2​−y1​​📖
