Flashcard 1 - Upper Level: Mathematics Achievement Flashcard Set for the ISEE

Determine the slope of a line by solving for the change in y over the change in x, or:

\[slope = \frac{y_2 – y_1}{x_2 – x_1}\]

where \((x_1, y_1), (x_2,y_2)\) are points on the line.

For easy memory recall: “Slope equals rise over run.”
