Answer:
The distance between (9,1) to (1,8) is 3.26
Explanation:
To solve this exercise we first have to calculate the distances between the factors of x and those of y
(x , y)
P1 = (9 , 1)
P2 = (1 , 8)
To calculate the distance we have to do P1 - P2
(9 , 1) - (1 , 8)
we subtract the corresponding from each other
9 - 1 = 8
1 - 8 = -7
(8 , -7)
Now that we have obtained these values, what we have to do is Pythagoras, since x represents a horizontal displacement, and y represents a vertical one, and the distance will be the hypotenuse that is formed from them.
h² = 8² + (-7)²
h² = 64 + 49
h² = 113
h = √113
h = 3.26
The distance between (9,1) to (1,8) is 3.26
