What is the distance between these two points?
(1,4) , (-2,-1)
(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}
