Front

What is slope?

Back

What is the formula for calculating slope?

Back

The formula for slope (m) is: m = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are two points on the line.

Calculate the slope between the points (1, 2) and (3, 6).

Back

The slope is 2, calculated as (6 - 2) / (3 - 1) = 4 / 2 = 2.
