Question

What is the length of the line segment PQ on the coordinate grid?

Answer 1

Using the formula for the distance between two points, the length of the line segment PQ is of 30 units.

What is the distance between two points?

Suppose that we have two points, $(x_1,y_1)$ and $(x_2,y_2)$. The distance between them is given by:

$D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

The coordinates of the endpoints for this problem are given by:

• P(-20,10).

• Q(10,10).

Hence the distance is given by:

D = sqrt[(-20 -10)² + (10 - 10)] = 30 units.
