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 rise over run. when given two points, you can determine the rise by finding the difference between the x - coordinates. you can determine the run by finding the difference between the y - coordinates.

Explanation:

The slope of a line between two points $(x_1,y_1)$ and $(x_2,y_2)$ is given by the formula $m=\frac{y_2 - y_1}{x_2 - x_1}$, where the numerator $y_2 - y_1$ represents the rise (vertical change) and the denominator $x_2 - x_1$ represents the run (horizontal change). So slope is the ratio of rise over run, with rise from $y$-coordinate differences and run from $x$-coordinate differences.

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.
