Question

100 POINTS AND BRAINLY NO LINKS What is the length of the line segment with endpoints (−3, −8) and (10, −8) ?

Answer 1

Answer:

10 units

Step-by-step explanation:

$(x_1,y_1)=(-3,-8)$

$(x_2,y_2)=(10,-8)$

We are supposed to find the length of the line segment with endpoints (−3,8) and (7, 8)

We will use distance formula : $d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Substitute the values :

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

$d=\sqrt{100}$

$d=10$

Hence the length of the line segment with endpoints (−3,8) and (7, 8) is 10 units

Answer 2

Answer:

13 units

given two points: (−3, −8) and (10, −8)

As the y coordinates are same.

use the method:

|x2| + |x1|  where  (x1, y1), (x2, y2)

Solve:

|10| + |-3|

10 + 3

13
