What is the distance between these two points? (1,4) , (2,1) The distance formula:D = √[(x2  x1)² + (y2  y1)²] the points have coordinates of (x1,y1) and (x2,y2) (1,4) , (2,1) D = √[(2  1)² + (1  4)²] {substituted into the distance formula} = √[(3)² + (5)²] {subtracted} = √[9 + 25] {squared 3 and 5} = √34 {added 9 and 25} ≈ 5.83 {evaluated square root of 34} © Algebra House
