m = (y₂ − y₁) / (x₂ − x₁)
y = mx + b
Slope represents the steepness of a line in coordinate geometry. It tells how much the y-value changes when the x-value increases.
Slope is also known as rise over run where rise represents vertical change and run represents horizontal change between two points.
A positive slope indicates the line goes upward from left to right, while a negative slope indicates the line goes downward.
Slope is widely used in algebra, physics, economics, engineering and data science to represent rate of change.
