Question

Question 2 (3 points) What is the length of the segment whose endpoints are A(2, -3) and B(10, 7)?

Answer 1

Answer:

$d = \sqrt{164} = 12.8$

Step-by-step explanation:

We can find the distance using the distance formula:

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

We then substitute (2,-3) as $(x_1,y_1)$ and (10,7) as $(x_2,y_2)$.

$d=\sqrt{(10-2)^2+(7--3)^2} \\d=\sqrt{(8)^2+(10)^2} \\d=\sqrt{64+100}\\d=\sqrt{164}=12.8$
