Calculate the distance between point j(-2,-4) and k(-5,-10) in space ?

To calculate the distance between two points in space, we can use the distance formula:

d = √((x2 - x1)^2 + (y2 - y1)^2)

In this case, the coordinates of point J are (-2, -4) and the coordinates of point K are (-5, -10).

Plugging these values into the distance formula, we get:

d = √((-5 - (-2))^2 + (-10 - (-4))^2)
= √((-5 + 2)^2 + (-10 + 4)^2)
= √((-3)^2 + (-6)^2)
= √(9 + 36)
= √45
≈ 6.71

Therefore, the distance between point J(-2, -4) and K(-5, -10) in space is approximately 6.71 units.
