FLASHCARD QUESTION

Front

What does the slope of a linear function represent?

Back

The slope of a linear function represents the rate of change of y with respect to x. It indicates how much y increases or decreases for a unit increase in x.

FLASHCARD QUESTION

Front

What is the y-intercept of a function?

Back

The y-intercept is the point where the graph of the function crosses the y-axis. It is represented as (0, b) in the equation y = mx + b.

FLASHCARD QUESTION

Front

If a function has a slope of -3, what does this indicate about its graph?

Back
