What does the slope of a line represent?

Back

The slope of a line represents the rate of change of the dependent variable (y) with respect to the independent variable (x). It indicates how steep the line is.

How do you graph a linear function?

Back

To graph a linear function, identify the y-intercept (b) on the y-axis, use the slope (m) to find another point, and draw a straight line through these points.
