13 units.

The answer above is correct!

Step-by-step explanation:

Answer 2

Answer:

EF = 13 units

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

Length of segment EF = $\sqrt{(-7+2)^2+(-5-7)^2}$

                                     = $\sqrt{(-5)^2+(-12)^2}$

                                     = $\sqrt{169}$

                                     = 13

Therefore, length of segment EF is 13 units.
