Free interpolate between data points calculator to interpolate between data points. Instant results in your browser — no signup. Linear interpolation assumes constant slope between two points.
Linear interpolation assumes constant slope between two points.
(0,0) to (10,50) at x=4 → y=20.
Works outside [x₁,x₂] but assumes the same slope — use cautiously.
