Front

What does the slope (m) represent in a linear function?

Back

The slope (m) represents the rate of change of y with respect to x; it indicates how steep the line is.

Front

What is the y-intercept in the Slope-Intercept Form?

Back

The y-intercept (b) is the value of y when x = 0; it is the point where the line crosses the y-axis.

Front

What is the significance of the slope being positive, negative, zero, or undefined?

Back

A positive slope indicates the line rises, a negative slope indicates it falls, a zero slope indicates a horizontal line, and an undefined slope indicates a vertical line.

Front

What is the relationship between parallel lines in terms of slope?

Back

Parallel lines have the same slope; they never intersect.
