How do you find the slope between two points (x1, y1) and (x2, y2)?

Back

The slope is calculated using the formula m = (y2 - y1) / (x2 - x1).

How can you determine if a line is increasing or decreasing from its slope?

Back

If the slope is positive, the line is increasing; if negative, the line is decreasing.
