Answer:
√85
Step-by-step 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
