Answer:
Hope this helps.
Step-by-step explanation:
The length of the line is 5.
Find the difference between coordinates:
(x2 - x1) = (6 - 1) = 5
(y2 - y1) = (8 - 8) = 0
Square the results and sum them up:
(5)2 + (0)2 = 25 + 0 = 25
Now Find the square root and that's your result:
Exact solution: √25 = 5
Approximate solution: 5
