Slope Formula

也称为: Gradient Formula, Rise Over Run

m = \frac{y_2 - y_1}{x_2 - x_1}

m = (y₂ - y₁) / (x₂ - x₁)

它计算什么

Measures the steepness of a line — how much y changes per unit change in x.

象征	姓名	单元	描述
m	Slope	—	The steepness or gradient of a line
(x_1, y_1)	Point 1	—	First point on the line
(x_2, y_2)	Point 2	—	Second point on the line

1m = (9 - 3) / (5 - 2) = 6/3 = 2

结果: m = 2
