Question

M {-5,2} and N {5,2} are the endpoints of the segment MN on the coordinate plane what is the length of MN?

Answer 1

Length MN = 10 unit

Explanation:

Given: M {-5,2} and N {5,2} are the endpoints of the segment MN.

Length of line segment having co-ordinates as

`(x_1, y_1) and (x_2, y_2)`

is calculated as

`D =√((x_2-x_1)^2+(y_2-y_1)^2)`

So plugging the values in above equation we get

`D =√((5+5)^2+(2-2)^2)`

D = 10 unit

Therefore, Length MN = 10 unit
