What does the slope of a linear function represent?

Back

The slope of a linear function represents the rate of change of the function. It indicates how much the y-value changes for a unit change in the x-value.

Front

How do you find the slope from a table of values?

Back

To find the slope from a table of values, use the formula: slope (m) = (change in y) / (change in x) between two points.

FLASHCARD QUESTION

Front

What is the y-intercept of a linear function?

Back

The y-intercept is the point where the line crosses the y-axis. It is represented by the value of b in the equation y = mx + b.
