Work out point slope form instantly with clear inputs, formula shown and shareable results.
Point-slope form y − y₁ = m(x − x₁) is the most direct way to write a line through a known point with a known gradient. Expanding it gives slope-intercept form with c = y₁ − m·x₁.
Point-slope form
y − y₁ = m(x − x₁)
y + 2 = 0.5(x − 4), which simplifies to y = 0.5x − 4.
Whenever you have a point and a gradient, since it avoids the extra step of computing the intercept.
