To help Briella remember the formula for slope, the correct explanation is:
Slope is the ratio of rise over run. When given two points, you can determine the rise by finding the difference between the y-coordinates. You can determine the run by finding the difference between the x-coordinates.
This explanation accurately describes how to calculate the slope using the differences in the y-coordinates for rise and the x-coordinates for run. The formula for slope (m) is given by:
\[ m = \frac{\text{rise}}{\text{run}} = \frac{y_2 - y_1}{x_2 - x_1} \]
where \( (x_1, y_1) \) and \( (x_2, y_2) \) are two points on a line.
