parallel and perpendicular lines quick check
briella is trying to remember the formula for slope. which of the following explanations of slope could help her figure out the formula? (1 point)
slope is the ratio of run over rise. 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.

Explanation:

The slope of a line between two points $(x_1,y_1)$ and $(x_2,y_2)$ is defined as the ratio of the vertical change (rise) to the horizontal change (run). The rise is calculated as $y_2 - y_1$ (difference in y - coordinates) and the run is calculated as $x_2 - x_1$ (difference in x - coordinates). So slope is the ratio of rise over run.

Answer:

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.
