Question

Find the distance between the points (3, –8) and (0, –9).

Answer 1

Answer:

B. 3.16

Step-by-step explanation:

1) formula of the required distance is:
$d=\sqrt{(X_A-X_B)^2+(Y_A-Y_B)^2} ;$

2) if A(3;-8) and B(0;-9), then according to the formula above:

$d=\sqrt{(0-3)^2+(-9+8)^2} =\sqrt{10}.$

d≈3.16
