What is the slope of a linear function?
Back
The slope of a linear function is a measure of how steep the line is. It is calculated as the change in y divided by the change in x (rise over run).

FLASHCARD QUESTION
Front
What is the y-intercept of a linear function?
Back
The y-intercept of a linear function is the point where the graph crosses the y-axis. It is represented by the value of b in the equation y = mx + b.
