Answer:
10.63
Step-by-step explanation:
d = √((x2-x1)2 + (y2-y1)2)
Step by step procedure:
Find the difference between coordinates:
01(x2-x1) = (-1 - -9) = 8
(y2-y1) = (1 - 8) = -7
Square the results and sum them up:
(8)2 + (-7)2 = 64 + 49 = 113
Now Find the square root and that's your result:
Exact solution: √113 = √113
Approximate solution: 10.6301
