Question

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

Answer 1

10 units

Step-by-step explanation:

[tex](x_1,y_1)=(-3,-8)[/tex]

[tex](x_2,y_2)=(10,-8)[/tex]

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

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

Substitute the values :

[tex]d=\sqrt{(10+3)^2+(8-8)^2}[/tex]

[tex]d=\sqrt{100}[/tex]

[tex]d=10[/tex]

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

Answer 2

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
