Formula
Slope: m = (y₂ − y₁) / (x₂ − x₁). Y-intercept: b = y₁ − m × x₁. Line: y = mx + b. Angle: θ = atan(m).
Domande Frequenti
How do you calculate the slope of a line?
Divide the change in y by the change in x: m = (y₂ − y₁) / (x₂ − x₁).
What is the y-intercept?
The y-intercept b is where the line crosses the y-axis. It equals b = y₁ − m × x₁.
What does a slope of zero mean?
A slope of zero means the line is horizontal — there is no rise between the two points.
What if x₁ equals x₂?
When x₁ = x₂, the line is vertical and the slope is undefined (division by zero).
