Question

What is the length of segment AB
A. 5
B. 6
C. 8
D. 10​

Answer 1

Answer:

D. 10

Step-by-step explanation:

The formula of a distance between two points:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

From the graph we have the points A(6, 2) and B(0, 10). Substitute:

$AB=\sqrt{(0-6)^2+(10-2)^2}=\sqrt{(-6)^2+8^2}=\sqrt{36+64}=\sqrt{100}=10$

Answer 2

The length is D. 10

√ (x2 - x1)^2 + (y2 - y1)^2

√ (0-6)^2 + (10 - 2)^2

√ (-6)^2 + (8)^2

√ 36 + 64

√ 100 = 10
