Distance between point (4,2) and (4,-2)?
Given - Two points be $A(4,2)$ and $B(4,-2)$
Solution- Using formula, $AB = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$
Substitute the coordinates: $\sqrt{(4 - 4)^2 + (-2 - 2)^2} = \sqrt{0 + 16} = \sqrt{16} = 4$
Therefore, the distance between the two points is $4$ units.
