What is the significance of a slope of zero in a linear function?

Back

A slope of zero indicates that there is no change in the dependent variable as the independent variable changes; the line is horizontal.

How can you calculate the slope between two points on a graph?

Back

The slope can be calculated using the formula (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are the coordinates of the two points.
