Question

Find the distance between the two points in simplest radical form. (3,8) and (5, -1)​

Answer 1

√85

Explanation:

d = √((x2-x1)2 + (y2-y1)2)

Step by step procedure:

Find the difference between coordinates:

(x2-x1) = (5 - 3) = 2

(y2-y1) = (-1 - 8) = -9

Square the results and sum them up:

(2)2 + (-9)2 = 4 + 81 = 85

Now Find the square root and that's your result:

Exact solution: √85 = √85

Approximate solution: 9.2195
