Question

Point E is located at coordinates (-7,-5). Point F is located at coordinated (-2,7) what is length EF

Answer 1

13 units.

The answer above is correct!

Explanation:

Answer 2

EF = 13 units

Explanation:

Points E and F are the ends of segment EF.

Coordinates of E → (-7, -5)

Coordinates of F → (-2, 7)

Since, length of a segment joining points
`(x_1,y_1)` and
`(x_2,y_2)` is given by,

Length of segment =
`√((x_1-x_2)^2+(y_1-y_2)^2)`

Length of segment EF =
`√((-7+2)^2+(-5-7)^2)`

=
`√((-5)^2+(-12)^2)`

=
`√(169)`

= 13

Therefore, length of segment EF is 13 units.
