Slopey Slope

Front

What is the formula to calculate the slope of a line between two points (x1, y1) and (x2, y2)?

Back

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

How do you find the slope of a line given two points (10, 1) and (5, 2)?

Back

Use the formula: m = (y2 - y1) / (x2 - x1). Here, m = (2 - 1) / (5 - 10) = 1 / -5 = -1/5.

What is the slope of the line that passes through the points (6, 7) and (4, 2)?

Back

The slope is calculated as m = (2 - 7) / (4 - 6) = -5 / -2 = 5/2.
