The length EF is 13 units
The coordinates of the points are given as:
Point E = (-7,-5)
Point F = (-2,7)
The length EF is calculated using the following distance formula
[tex]EF =\sqrt{(x_2 - x_1)^2 + (y_2 -y_1)^2}[/tex]
This gives
[tex]EF =\sqrt{(-2+ 7)^2 + (7+5)^2}[/tex]
[tex]EF =\sqrt{169}[/tex]
Evaluate the root of 169
[tex]EF =13[/tex]
Hence, the length EF is 13 units
