d ² = (- 2 + 4) ² + (2 + 4) ²
d ² = 4 + 36
d ² = 40
d = 2â10

You might need to memories the distance formula, depending on your teacher.
distance=â[(x1-x2)^2+(y1-y2)^2]
this problem is
distance=â[(-4+2)^2+(-4-2)^2]
=â[(-2)^2+(-6)^2]
=â(4+36)
=â(40)
This is the correct answer, but I like to simplify and so do teachers
=â(4)â(10)
=2â(10)

sqrt ( (-2-(-4))^2 + (2- (-4))^2)
sqrt ( (2) ^2 + 6 ^ 2
= sqrt ( 4 + 36
= sqrt 40 = 2 * sqrt 10
