Describe how the rise over run method is used to calculate the slope of a line.

• Slope is calculated by multiplying the change in y-values by the change in x-values using the formula (y2 - y1) * (x2 - x1).

• Slope is calculated by taking the square root of the change in y-values divided by the change in x-values using the formula √(y2 - y1) / (x2 - x1).

• Slope is calculated by adding the change in y-values to the change in x-values using the formula (y2 + y1) + (x2 + x1).

• Slope is calculated by dividing the change in y-values by the change in x-values using the formula (y2 - y1) / (x2 - x1).
