Question

The coordinates of the point K are (-8, 2) and the coordinates of point L are(10,2). What is the distance, in units, between the point K and point L?

Answer 1

Given:

The coordinates of the point K, (x1, y1)= (-8, 2).

The coordinates of the point L, (x2, y2)=(10, 2).

The distance between points K and L can be calculated as,

$\begin{gathered} KL=\sqrt[]{(x2-x1)^2+(y2-y1)^2} \\ KL=\sqrt[]{10-(-8))^2+(2-2)^2} \\ KL=\sqrt[]{18^2+0} \\ KL=18 \end{gathered}$

Therefore, the distance between point K and L is 18 units.
